What is the difference between switch and switch or how to control lighting from several places. CHARACTERISTICS AND SCHEME OF CONNECT REDUCE Switch Circuit breaker circuit

Switches in electrical engineering are used to shut down and turn on low voltage circuits alternately. For example, the passing switches are designed for the convenience of lighting control in various rooms, stairs, corridors. Such electrical switches are mounted between the floors, near the doors of rooms with several inputs.

It is convenient to manage other rooms from the house as well. Switches allow you to manage the functioning of the lighting, while in the other place, which creates certain convenience and comfort, and the electricity is saved.

A simple switch has a key to two positions and one pair of contacts to which the conductors are connected. Switch, unlike switch, has three or more contacts. One contact is common, the rest are overhead. Wires are connected to each of these contacts. To control the lighting from other places, you need a switch to several contacts. Electrical switches allow you to control the operation of any electrical devices, and not just lighting.

Operating principle

Electric switches work as follows. The meaning of their work lies in the echoing of the main contact with one chain to another. Most often, on the reverse side of the switch housing, the wire connections circuit is depicted.

One Contact Common (1), other two contacts - cake (2 and 3). Using two such switches, and placing them in different places, you can perform the most popular and simple lighting scheme of two different places.

Coinciding on the designations of terminals 2 and 3 with switches PV-1 and PV-2 are connected by conductors among themselves. Input 1 from PV-1 is connected to the phase, and PV-2 is connected to the lighting fittings. The other end of the lamp is connected to the zero network conductor.

Schema performance check is carried out by turning on the switch. First, the voltage is supplied, while the lamp lights up and goes out from a separate action of any of the switches. When opening a chain of one of the switches, another line of the chain is included in the operation.

Species and design features

To properly select the switch, it is necessary to determine the type of control of the control of the handle, solved by tasks, the diagram of the compounds, the properties of the connected circuits.

There are electrical switches divided by types by the type of control of the handle:

Corner.
Pressure.
Swivel.

Corner switches of the type of the toggler are manufactured in two schemes:

With dumping contacts (drawing "A").
Rubber type (drawing "B").

Both types of switches have two stable positions of the handle. When the handle is moved (1), the spring (2) is compressed, concentrating the compression energy. When found in the position shown by the dotted line, the device is in unstable equilibrium.

A small shift of the handle and spring dramatically moves moving contact (3) to a stable position. As a result, movable contact is jumpingly connected to a fixed contact (6).

According to the connection scheme, the toggle switches with dumping contacts are divided into:

Single-pole (drawing "A").
Single-pole dual (drawing "b").
Two-pole into two positions (drawing "B, G").

The handles of these switches can be in two fixed positions. Switching patterns can be the most different. Tamblers are used to switch the AC and DC schemes. They are able to withstand the load in the current circuit of up to 6 amps. The resistance of their contacts is very small (0.02 ohms).

The reliability of the work of the togglers can be expressed by a possible number of switching, which reaches 10,000 times.

Microtumbers

Such small sizes are won in dimensions and mass, compared with other types of togglers.

Electric push switches

Electric switches in the form of buttons are classified by type of control:

Normal. The circuit is open or closed only when pressed.
Sharpening. The chain is closed in the absence of pressing effort. To open the chain, it is necessary to press again.
Dual. The circuit closes when you press one button, opens with another button. The button of the buttons is based on the toggle switches, microswitches. In addition to the main, there are original devices.

Connection schemes of conventional and sticking buttons are divided into:

Single-pole inclusions (drawing "A").
Shutdown (Figure "B").
Turning on-off (drawing "B").
Two-pole inclusions (drawing "G").

Pressure switches are performed with protection against dust and moisture, and without protection.

Swivel switches

Haltage switches electric

Among the electric switches of the turning point are the greatest popularity of gallery switches. With their help, you can simultaneously connect several electrical circuits related to each other.

The gallery switch device is designed in such a way that the metal ring (2) with the protrusion is rigidly connected to the axis (1) of the switch. The total number of contacts located 30 degrees - 12 pieces. When turning the axis by 330 degrees, a general output is switched out with 11 different circuits that are connected to contacts (4).

There are some modifications of gallery switches. For example, the ring can be performed cut. Each part is the protrusion. When the axis is rotated, two general outputs are synchronously connected to 5 different chains.

In the gallery rotary switches, cutting knife contacts are used, which are made of copper alloys (bronze, brass), coated with a layer of silver. The knife contact makes it possible to reduce the effect of the error of manufacturing assembly and parts, increase its vibration resistance and reliability.

Galette switches are capable of switching electrical circuits of current up to 3 amps, voltage up to 350 volts of DC. For alternating current, the allowable voltage is no more than 300 volts. The reliability of such switches is up to 10,000 switching.

The installation of the switches is made by soldering, in addition to the toggle types of switches, which are connected to the circuit with screws. The main requirement of the mechanical installation of the switches is the requirement: Do not change the position of the housing and the inner part of the switch when the management force is applied. In this regard, when using the switch, it is necessary to use only those fastening methods that correspond to the specifications of a specific type of switch.

Lighting Switch Scheme

To mount switches in three places you need an auxiliary device with crosschair circuit. Such a device consists of two 1-keys switches with internal jumpers made in one case.

The cross switch is mounted between 2 ordinary. It is used only with them, and is distinguished by the presence of 4 terminals. To control the lighting of 4 points, you must add the same device to the diagram. The cross switch connects to the cake of the switches contacts in such a way that the lighting power supply circuit formed.

Sophisticated contact groups need a large number of guides and connections. The optimal option will be the assembly of several simple schemes, instead of one difficult, as they will work more reliably, and more convenient in operation. All basic must be produced in. Wire twists are not allowed.

The passage switch is a special type of electropurture, which is also often called duplicate or cake.

The passage switch and switch differs in the fact that when using a switch, you can only closure or smolden the chain, while the passage switch is equipped with three contacts, as well as switching mechanism. The rebound switch allows you to control a single lamp or a group of lamps from different places.

Scope of use of passing switches

The passage of the lighting switch in the apartment or house can be used in different cases:

on the stairs. Switches are located on different floors - a person includes light below, rises and turns it up at the top;
in the bedroom. One switch is located at the entrance, the other - in the bed;
in a long corridor. Switches are installed at different parts of the corridor.

In addition, the external lighting switches are also used, which are mounted to illuminate tracks, different inputs, etc.

Types of passing switch

Currently, there are several types of switches, both in appearance and on the device. There is a single block and a two-vector passage switch, the connection diagram of which is somewhat different.

The duplex switch has six contacts and is essentially with a connection of two classmate switches. It allows you to manage multiple lamps and stages to include them.

There are also cross-switches that have four contacts and allow you to turn on the lamp of three places. In such a scheme for turning on the lighting device, you will need 2 passing switches and 1 crossbar.

In addition, the passing switches differ in appearance - there are key-button, keyboards, swivel switches, and selecting a specific type depends on the preferences and needs of the owners.

Currently, there are a large number of companies implementing qualitative variants, such as the LEGRAND switch, the connection circuit of which is not different from the schemes of other brands.

How to design the passage switch?

When repairing an apartment or construction of a new house, you must immediately determine where the passage switches will be located. Since the switch connectivity scheme involves the use of more cable, so it is necessary to think about it before the electrical installation works will begin.

It is also necessary to decide whether access to lamps is needed, and how many devices will be under its control. After you have defined all the moments, you will need a circuit of the passage switch, suitable for your plan.

How to connect passage switch?

As mentioned above, the circuit of connecting the passage switch with three and six contacts is somewhat different. In addition, the circuit of the passage switch of light depends on the number of points from which it can be controlled by light.

Consider classroom electrical switches. Because the passing switches switches from one chain to another, it is necessary to provide the first passage switch with power, and from the second switch will leave the phase wire connecting to the wire from which the light is powered by a light bulb in the junction box. Also, the switches are connected to each other using a two-core cable. For more details, see the circuit.

If you want to switch light from several places, you will fit the following scheme. It looks like the previous one. However, in this case, two input contacts and two weekends must be made in the switch.

The diagram of connecting two-layer switches is also not very different from the classic. In fact, this scheme is the connection of two classmate switches and allows you to control two lights from two places with two lighting devices.

Where to place the switch? This is a difficult question if you need to turn on-off the light in a large hall that has several inputs, or in a long corridor. If the switch is one, and there is a lot of space, it is inconvenient.

And is it possible to do better - to turn on-turn off the light from different ends of the corridor or stairs at the entrance, at the local area from the house, garage, from the wicket and so on? Our digital age immediately come into mind radio-controlled consoles, motion sensors, and so on. It is fine, but you can do easier, cheaper and more convenient. You just need to use the passage switch.

Many of us met the circuit of the passing switch in the school task. In the task for the seventh class, it is proposed to create a diagram at which you can turn on and off the light bulb at any end of the corridor. To understand the principle of operation of the passage switch, we will analyze the solution of this simple task.

At first - a simple "One light and one switch" scheme:

The K1 key is closed, the light bulb is glowing. If you smoke contacts - the lamp will go out. Using such devices, the task to turn on-off from different ends of the corridor is not to decide: even if we can turn on the light with different switches, we will not be able to just turn it off.

A pair of passing switches

To solve the task, do not need switches, but switches, and still need an additional wire. The switch transmits a voltage to one of two wires:

Here the phase is transmitted from contact 1 to 2. If you click the switch, then the voltage from contact 1 will go to 3.

With any position of the switch, only one of the wires will be under voltage: 2 or 3.

This is the electrical circuit of the passing switch: a simple switch.

But for the work you need even one light light switch. From the first switch you need to stretch two wires.

What happens if we right-click 1? The chain will open. And if the switch 2? Same.

So, light can be turned off from any end of the corridor. And then you can turn it on by clicking any of the switches. For example, the first:

TRANSFER TRANSFER MOREWORN NOT HAVES ON, OFF. Any commutation of one of the pairs of switches changes the state of the system: if the light is burned, it will go out, and if it turned off - it will light up.

What to buy to implement the scheme

Understanding how the passage switch works, you can independently mount the scheme of convenient lighting control. In the market of electrical products, products are popular for several companies, such as LEGRAND passing switches. They are functional, have an attractive design, some with LED backlight.

LEGRAND VALENA passage switch, if it is without a pair, can work as simple. But usually they buy them in pairs.

Buyers are often asked than the externally different switching switch from the usual one. Differences Little: Enterprises use a single case design for different devices. There is no marking on the passing, indicating the inclusion (sometimes it is still there, due to the use of standard components, but they do not pay attention to it). Differences in the connection of electrical contacts can easily determine the person familiar with the electrical engineering.

The figure shows the connection of the LEGRAND passing circuit breakers operating per group of lamps.

The passing switches, as well as ordinary, are produced from one or two keys. Two-block controlled two groups of lamps. You can, for example, adjust the lighting brightness, including and disconnecting the bulbs in the chandelier.

No worse than the products of other firms: Lezard, Lexman, ABB, Schneider Electric.

LEZARD passing switches are connected along the same scheme as Legrand made by Legrand and other firms.

Collect the scheme from devices from any manufacturers is very simple, but sometimes there are difficulties, because there are schemes with errors on commercial sites on the Internet. Sometimes cheap Chinese devices are accompanied by paper instructions with errors in the schemes.

Use the simplest scheme on which everything is clear that you understand.

Turn on and turn off the light of ten places

We examined in detail the switching scheme of lamps from two different places.

But is it possible to do so that the light is turned on-turned out of three, four beds and so on? For example, when leaving the apartment, on any floor, turn on the light on the stairs, and when you exit the entrance to turn it off. And also to do in the reverse order: turn on the light at the entrance to the entrance, and turn off your door. Or late in the evening, leaving the office in the corridor, where the prevailing rash is turned off the light, do not break in the dark, and click the switch from its door, and there will be a light! And turn off later at the output. And so that these switches in the corridor were somewhat - in different doors.

To organize such lighting, you need to use more complex passage switches, they are called cross. Consider their functioning.

The cross switch is such a thing that has two input terminals and two outputs. A phase comes to one entrance to another - an empty wire, in any order.

Accordingly, we have at the outputs: on the same phase, on the other - nothing. By clicking the cross-switch key, we swap in the phase and "empty" in the weekend.

If you place the cross switch between the two passages, then three switching points will be. Each switch, if you change its status, changes the lighting: if the light burned, it will go out, and if it turned off - turns on.

Look at the drawing. At the moment, the circuit is closed, but what will happen if you click any of the three devices? The chain between the entrance and the output will open, and the light will go out.

Interestingly, after turning off, we can turn on the light, again clicking any switch.

You can put two cross-switches in the middle of the circuit, three, four .... how much is not a pity. And any switch will change the system status.

It may seem amazing, especially since the long chain of switches is not easy to figure out. But nevertheless, the scheme works! After all, if at no position of the commuting phase, the phase is "lost" - it comes to one of two outlets of each cross-switch, and only the last passage "selects" phase or its absence.

Overhead cross switches are in demand

The passing switches are produced in the same housings as the usual. There are overhead models and embedded, in performances for internal and outer wiring. The overhead models of passing and cross-switches are in demand, because they are used in large quantities when improving the lighting systems, including the external lighting device.

When building your home, a convenient switching system with passing switches can be applied to the electrical wiring project.

New technologies: Touch passing switches

Stylish sensory switches are more expensive than usual, but in demand - they have become a natural part of modern "digital culture".

Sensory devices are quite complex electronic devices. For current switching, a thyristor or a high-power transistor is used, and the signal, thanks to which opens (or locks), the device comes from the sensor - the sensor responding to any external impact.

The sensor can be a motion sensor, or acoustic, or capacitive - reacting to touch. Sensitive sensors react even before touching, it is enough to bring a hand at a distance of 1-3 centimeters. In homes, capacitive sensory switches are usually installed, or combined with motion sensor. All sensory devices can be remotely controlled. If the control panel is not included, it is bought separately.

The semiconductor device responsible for turning on-turning off the current can also be used to control the current force, the brightness of light, if equipped with a dimmer. It is important to know that dimmers are not suitable for all lighting devices.

Passing and cross-sensor switches, as well as mechanical, are used to control lighting devices from different points. Compared to mechanical, they are more functional: can be controlled remotely, control the power of light.

Externally, sensory devices are a smooth panel of glass, in the connected state it is noticeable to display: Blue Fireflux - the state of the off, red - incl. To control the lighting device, you just need to touch the device panel.

In the photo - the touch switch.

The paradox consists in the fact that technologically advanced sensory devices are perfectly coping with the control of incandescent lamps or gas-discharge, but when the advanced LED lamps are turned on, problems occur. In the "Touch switch - the LED lamp" in the disconnected state, weak electrical impulses may be guided, due to which the LEDs are winking. Sometimes problems with dimmer arise if it adjusts the current through the LEDs.

The figure shows the diagram of connecting the adapter parallel to the LED lamp.

In this picture, the adapter is connected to the distribution box and affects all LEDs included in this chain.

Consider the schemes for connecting passage sensor switches.

Here is shown the connection of two sensor passing switches.

Here is shown the connection of three passing sensor switches.

Note that in the middle there is the same sensory switch, as in the edges. That is, sensory devices are not divided into "simple" and "cross".

In the touch switches, there is a "main" - which is shown on the left, three wires are suitable for it (one wire - from the load). Before starting work, the system needs to synchronize. Touching the main device panel, 5 seconds are waiting for a beep. After that, you need to touch the second switch. Synchronization is manufactured. Further synchronize the third, fourth switch, and so on.

Passing outlet is very simple

Having become acquainted with the wonderful properties of the passing switches, we are waiting for miracles and from such an object as a passing outlet. But there is nothing special here. It is just there is an end socket (electrical wires are suitable for it that do not go anywhere), and the passage - it is connected to the wiring, which is connected to a few more sockets.

Passing outlets do not have any constructive, no circuit features. The name simply reflects their place in the power supply system.

What limits the number of passing switches

The chain of the switches allowing you to switch the electrical current from several points, should not be too cumbersome. Contacts have electrical current resistance. It is small, but on the long chain of contacts current can decrease markedly. With a large number of switches included with each other, the reliability of the circuit decreases, malfunctions are possible. Therefore, we rarely meet the strip of passing and cross-switches in ten or more pieces. Most often it is a pair of switches, somewhat less often - a chain of three, four, five.

The use of these devices makes life more convenient and saves electricity.

Types of passing switches

So, we looked at different variants of this device class. In completion, we list their types.

By technology:

mechanical;
semiconductor (sensory, with remote control).

By the number of independent loads:

one-centered;
multino (on 2, 3 groups of lamps).

In addition, mechanical switches are two types:

simple passing;
cross.

Connect the passing switches is very simple. Good luck!

To control lighting devices on the stairs or in a long corridor, a regular scheme with one "on / off" device is not suitable. To turn off the light in such a situation, you will have to go back to the only switch in the room. Not too comfortable, agree?

By installing the passage switch, allowing you to control the bulbs from two places, you will significantly increase the level of comfort in your home or office. We will tell about how to competently pick up the device and how to install it correctly. In the article proposed, the article discusses popular connectivity options.

Before you go to the store lighting for the necessary materials, first it is necessary to understand the terminology and various power switching devices.

For most beginners electricians that the switch is that the switch is the same. However, they only look like each other. On the principle of action, these devices differ dramatically.

Household both switches and light switches look equally and have uniform enclosures, but are intended for fundamentally different connection schemes.

The usual "switch" is the simplest discharging / closing electrical circuit key. He has one incoming and one outgoing wire. Plus there are two- and three-block devices with a large number of contacts. However, these are just two or three collected together in a single housing of the switch.

The "switch" is a commuting device in which one incoming electrical panel switches to one of several outgoing chains. Often, a similar device is also called a "rebound switch", as it has a key to cross the contacts from one position to another.

At a minimum in such a single-wave device three contacts (one incoming and steam of emerging). If two keys, then the terminals are already six (steam at the inlet and four at the output).

Under the term "pass-through switch" is understood by several switches interconnected by a specific scheme. A similar switch is designed to turn on / off a single light source immediately from several points indoors or fenced areas with lighting.

Make a device from classic switches to save on the purchase, it is impossible, for this you need to use exclusively switches

As a result, the two-contact switch is designed to rupture one electrical circuit with a phase, by which the lighting light is powered. And the three-stroke switch is used to create new separate power circuits.

The first option is needed to stop supplying current on any chain, and the second is to switch between chains. Outwardly both devices look absolutely the same. This is a housing with one or more keys. In this case, the switch can be used in the switch mode, and vice versa is not.

It is impossible to make a three-contact device from a two-contact device. But to eliminate the use of one of the chains is quite acceptable. But to organize light management from several points, you need to buy only switching devices with three or more contacts.

Types of household commuting devices

Switches are keypad, keyboards and swivels. The first option is usually used only as a call at the entrance door. It is not suitable for controlling lighting.

But the second type for switching on / off light in a residential building - just what is needed. The swivel variety is more designed for production and utility rooms. Such products do not have a very presentable appearance.

By number of keys, the switches are:

classmate;
two-block;
three-block.

They are divided into ordinary (passing), combined and (intermediate). The first have three contacts. In the second, this triple terminals increases multiplication by the number of keys. And third inputs and exits two. The latter are designed for non-two schemes, but several points on light.

By type of control in private houses Lighting switches typically apply standard keyboards, but there are also models with sensors and remote control

According to the wiring circuit, the switches are for open () and hidden (built-in analogs) of the wiring. The first are mounted on the wall of the dowel-self-assembly, and the second are fixed in the submerged with the help of driving legs.

When you select Switches to connect along the passage switch circuit, it is necessary to competently select the number of keys (for each connected group one by one). If the control points in the plans to do two, then only a pair of conventional three-pin devices will be required.

If these points need more, then each such place for inclusion in a single system will have to additionally take an intermediate cross-apparatus.

In the overwhelming majority of cases, the household key key has two positions on the closure of one of the chain. But there are also modifications with a zero middle state. With this position, both contours are broken.

Marking on the switch housing

On the part of the switch, where contacts are located, there is usually a special label indicating the characteristics of the commuting product. At a minimum, it is the rated voltage and current, as well as the designations of clamps for wires.

If the switch is selected for schemes with fluorescent lamps, then the letter "X" or "AX" should be present in its marking (only "A" on the usual)

When the light is turned on in fluorescent lamps in the chain there is a sharp burst of the starting current. If LED or incandescent bulbs are used, then this jump is not so big.

Otherwise, the switch must be designed for similar high loads, otherwise there is a risk of burning contacts in its clips. That is why it is so important for luminescent electrolympics to choose special switches.

To install in the bedroom or corridor, the switch with IP03 is quite suitable. For bathrooms, the second digit is better to lift up to 4 or 5. And if the switch is installed on the street, the degree of protection should be no lower than IP55.

Contact clamps for electrical conductors on the switch can be:

screw with pressure plate and without it;
noiseless spring.

The first are more reliable, and the second strongly simplifies the performance of the electromotion. Moreover, the most optimal option is screw clamps with an addition in the form of a clamping plate. When tightening, they do not destroy the living wire with the tip of the screw.

According to guest requirements, if the conductor has a cross section of up to 1.5 mm, then use a screw clamp to connect to it with a screw switch, in which the end of the screw turns through the core, is unacceptable

Also in the labeling of the switches there are denominations of terminals:

"N" - for zero working conductor.
"L" - for a conductor with a phase.
"Earth" - for zero under the grounding of a protective conductor.

Plus, usually, using "I" and "O", the position of the key in the "Enabled" and "Disabled" modes are indicated. The manufacturer's logos and product names may be present on the housing.

Lighting control from several places

Mounting circuits for switching on light from different ends of the corridor There are several. The simplest of them implies the presence of switches keys in two places of the room and one luminaire line.

If the turning on the lighting should be done more than two, then the wiring of electrical wires will be somewhat more complicated. But here there is nothing special wise too.

If you follow the presented switches connecting schemes, you will not arise any special problems with the organization of controlling the lamp from several points - it is only necessary not to confuse

If using the passing switch, it is planned to supply a voltage to the chandelier with two or three separate sets of light bulbs, the diagram is somewhat complicated. Here you have to mount switches with multiple keys, and the terminals for wires are much larger there.

Scheme # 1: To turn on the light from two points

The easiest way to organize the control of the lighting device from two different places indoors. To do this, you will need only a pair of standard switches and several meters of wiring.

Plus, it will be necessary to comply with the simplest electrical installation rules to eliminate lesions of the current and guarantee the safety of the entire system in the future.

The scheme of the "passing corridor switch" with two switches is the most popular, it is used everywhere in the corridors and bedrooms, as well as on stairs and verandas

When implementing the outputs of both switches are connected by a pair of lived with two separate supply circuits. Then the wire with a phase is connected to the input of one commuting product, and the second input is the removal to the light bulb.

As a result, with any position of both keys, the total supply circuit of the "pass-switcher" power supply is either broken or connected. Light can be turned on and off from two different points.

Such a solution allows you to power the lighting device when you turn on only any single key. The second, on the other side of the room, it always commutes one of the existing lines.

Scheme # 2: For two lamps

The first scheme is the simplest and cheap in the implementation. It is used most often. However, if the lamps indoors are somewhat or light bulbs in the chandelier are divorced into two groups, then such a variant of the passage switch will not fit.

If you need to use meals into two separate lines of lighting lamps, you will have to resort to the installation of two-block switches with six contacts each

By installation technology and devices used, this scheme almost repeats the first basic option. Only the wires in this case will have more.

And in order to save a little on them, the switching wire on the first in the circuit is recommended to do with a jumper. Pull a couple of individual lived from the junction box will be too consistent.

If the lines with lamps are three, then change to three-block analogs. In the rest of the rest of the wire connection scheme remains the same, only their number increases.

# 3 scheme: for multiple switches

With two points on the inclusion of light and one or more lighting groups, everything is quite simple. There you need wiring and pair of switches. But if necessary, organize control from several seats will have to purchase another type of switching devices.

If the switches for one luminaire must be set several, then without the cross switch can not do. In this device, one of the chains is transit

In such extreme switches, ordinary passages are set, as in the first case. And between them, then the cross-analogue with four electrical wiring terminals is mounted.

When you click on the key in such a switching device, the connected contacts occurs and their short circuit is immediately crushed into a new supply chain. In addition to single-color cross-switches, there are devices and with a large number of keys. They are designed for schemes with several groups of bulbs.

However, in this case, there would have to connect much more to the terminals. And here it is extremely important not to imagine anything. For the correctness of the electrical installation, with such a wiring, it is necessary to monitor particularly carefully.

If you need another point for switching on / off, then another intersection is installed with the sequential connection of the wires to the already existing

Electricians recommend connecting the switches between themselves through the junction box. However, it is much easier to do it directly by means of a two-tier wire. Practice shows that such a compound is more appropriate and electrical engineering norms does not violate. And the consumption of electrical wires is reduced seriously.

Proven in practice the connection of the cross switch is given in, with the content of which we advise you to get acquainted.

Conclusions and useful video on the topic

The nuances of connecting the switches so that the lighting can be controlled from several points, a little. But they are. And they can not miss them on the installation of their species when making installation. To make you easier to understand all the intricacies of the schemes described above, we recommend that you need to view the above video.

Connection diagram of passing (cake) switches through a junction box:

Using the passing switches greatly simplifies the lighting control in a large room, making this process more convenient. Independently mount such a system of several switches and wires is easy. It is only necessary to choose a set of necessary switches.

And how did you choose the passage switch for installation in a country house, office or apartment? What was the decisive argument for you in choosing a device? Please write comments below the block below, place pictures on the topic of the article, share useful information and ask questions.

Often those people who want to spend electrical wiring in their home, choose a switch, guided by its own taste. People look at his designer design, color, quality of the material from which it is made. Then they bring the selected switch home, and problems begin. Why? Yes, because it turns out, the switches are all different, and you need to choose them not by their appearance, but according to their working functionality.

The industry produces switches of three types of functioning: passing, conventional, cross (or other intermediate). What is the difference between them? The following will be described all three types of these devices.

Normal switch

The operation of the ordinary switch is carried out when adjusting from one point. Simply put, a person presses the switch to pay off, and the electric chain, which children know from the lessons of physics, is bursting. When a person includes light, an electrical circuit, the opposite is restored. Simply an instrument for this purpose and come up with it. A typical switch can be used everywhere: in the residential room and production. This device is installed easily and quickly.

Switch passage

This type of switches is much more difficult. It is more correct to name this thing not switch, but switch. This device does not just turn off the electricity, but switches it, that is, it makes the electric current to flow into another channel. This type of switch switch adjusts the electrical current receipt is no longer with one, but from two points. That is, the chain is not interrupted, but simply electricity is redirected to another place. On the example it looks like this: a man comes into a long corridor, includes light. It takes place at the other end of the room, and the cloth there is another switch, it extends electricity.

However, it is not necessary to think that this type of switches is convenient only for large premises so that people do not have much to walk, including or turning off the light. Modern designers of premises advise them to install them and in ordinary apartments. Especially recently, such devices in bedrooms are popular. For example, a person comes, includes light, preparing to sleep. To lie down in bed, electricity should be turned off, and then go in the dark. Uncomfortable, you can stumble upon furniture, especially if a person came to someone and in the room for the first time. And with such a switch you can repay the light, already lying on the bed. Very comfortably. However, it is better to hire a professional to install such a system.

Cross (intermediate) switch

Such switches allow you to control electrical currents with three or more points. The intersection switch is shown both for large spacious rooms and ordinary homes and apartments. For example, it is often mounted in modern bedrooms. One switch is placed at the entrance to the room, and the other two, on the sides of the double bed. You can enable or disable lighting from each of these points. Someone will say that this excessive luxury, and someone on the contrary will find it very comfortable and rational.

When installing such a system, both passing and cross switches are used. And the passage goes on the sides of the scheme, and the crossbar is installed between them. And if you install, for example, at the inlet to the electrical circuit, the switch is not correct type (instead of the passing - cross or usual), then the system will not work. Here without the help of an experienced specialist can not do.

If we take out the results, the technical characteristics of all types of switches are forced to carry out the installation of wiring, take into account the following points:

1. Intermediate and passing switches when installing can perform the functions of a conventional switch. However, in a more complex electrical circuit, the intermediate switch will not be able to perform the functions of the passing switch.
2. If the electrical circuit is mounted, where the inclusion will be more than threepoints, the passage switches are installed on the edges, and transients only between them (for that they are called intermediate).
3. When installing the electrical circuit, which is planned to include passing or cross-switch switches, you will need a larger number of cable, since the current goes in several directions, and the switches simply redirect it.

Therefore, it is very important to clarify the type of switch during the seller to avoid unnecessary problems. The type of switch also indicate the accompanying documents. In strong doubts, you can ask for this documentation from the seller.

And if a person is not electrician by profession, then for the proper installation of a chain chain with switches of different types, it will be better and safer to invite a specialist.
