Wiring diagrams the flow switch with two or three places

Switching lights on the principle "came, I turned on - went and turned off" - is one of the variants of the effective use of electric energy. The functionality of such a control system is provided by the same traditional devices - switches, but structurally somewhat modernized.

Switching modernization allows you to switch the flow connection with two or three seats to control the light source of each individual point. Agree, this solution is particularly useful for the length of the room, such as a corridor.

We offer to understand the principles of connecting the flow switch on the two and three control points. The article shows the operating scheme of the organization of groups of light, but also describes the features of the implementation of switching projects.

Communicating switching light sources

The logic of power savings spent on light fixtures or other, it is due to the simple user actions.

If the light unit is needed, electricity is supplied to it by a simple contact closure switch. In another case, the opposite effect.

Communicating light switch

Switch lights - electric interpreted slang - pass switch. Provides a fundamentally new approach to exploitation of electrical networks areas intended for installation of lighting devices (+)

However, suppose that the premises (residential or other purposes) pass. Then the user devices include light at the entrance, but leaving the room through another door, no longer will be able to de-energize the circuit. There is irrational use of electricity.

But the situation is easily corrected. And to do this will connectivity option flow switch with two flat seats for pass encoding scheme.

The passage of the corridor room

Long corridors of premises for different purposes - potential targets for the unit light source control systems from different places. It is the operation of such facilities should edge pressing issue energy saving

For example, there is a room with a functional purpose - the corridor. Management is required to make a general group of lamps premises of two points - the first (entrance) and second (entrance) door.

Switching light from two locations

Lighting project corridor consists of two groups of light, so it is logical to apply in this case, to control the two dvuhklavishnyh switch.

Accordingly, in addition to it will require:

  • two podrozetnitsy;
  • one junction box;
  • trohzhilny cable.

Footage of electrical conductors should be calculated after drawing diagrams and wiring layout. It is recommended to purchase a cable with a small margin.

The control circuit groups through two light switches communicating dvuhklavishnye looks approximately as follows:

Management of the two places

The control circuit with two separate groups of light through dvuhklavishnye devices: N, L - classical electrical network; RK - junction box for cabling; L1, L2 - Lighting separate groups; P - Jumper; PV1, PV2 -dvuhklavishnye communicating switches (+)

Phase conductor is brought to dvuhklavishny device PV1. This switch having the configuration of two keys, respectively, has two common terminals of contacts and four terminals of changeover contacts.

At the first device common terminals connected together and connected thereto phase conductor. Terminal 1 PV1 changeover contact is connected to terminal wire 1 changeover contact PV2. Accordingly, pin 2 PV1 is connected to terminal 2 PV2, terminal 3 PV1 PV2 to terminal 3, and terminal 4 to terminal 4 PV1 PV2.

There are still two terminals on the second pass-through switch. Both - the general (common), and they are joined by the principle: each one light group (L1 and L2) lighting system. Already groups emanating from the light conductor circuit is closed to zero the electric bus network.

But this is only one possible circuit design. So, if you are using a light band can be arranged on the one-button circuit breakers.

Wiring using one-button-through switches is more economical in terms of material consumption. It requires fewer wires, since almost doubled compared to the previous solution, reducing the number of trunks.

But, at the same time, it is limited to the functionality of the lighting system itself.

Management of the two places one-button devices

The schematic for one light group using one-button switches: L, N, PE - classical distributing power to the three lines; RK - junction box; A1 - light group; PV1, PV2 - one-button switches (+)

However, this option can be used most often for the device as part of living quarters.

What is required for a device management system in one-button switch?

The answer is obvious:

  • one-button switches (2 pcs.);
  • podrozetnitsy (2 pcs.);
  • Distribution box (1 pc.);
  • electrical cable trohzhilny (yardage on the calculation).

the device standard system requirements. Before starting work charts. Acquired the necessary accessories, materials, fasteners. According to the target site set podrozetnitsy and junction box.

Installation of one-button devices

Example of wiring devices for residential premises from the category of standard designs. There are two one-button switch. The decision fulfilled in view of the cable wiring to the grounding conductor (PE). This embodiment corresponds to the circuit shown above

Then diluted with cable connections and run-through switches of two places to the light source via a junction box.

Phase conductor plant for PV2 common terminal and the common terminal PV1 is output to one terminal of the light band. The second contact group coupled light with a zero bus, and changeover contacts of both switches commute observing identical numbering (1, 1, 2 with 2).

The decision on the three control points;

Organization passage switching systems is largely determined by the area of ​​space (length), the number of turns (door). Therefore it is not excluded the use of schemes with passage control switches with three or more places.

Construction of such circuits is generally done with so-called cross switch.

This is the same switch, but the circuit engineering execution made five contact terminals, two of which are short-circuited jumper. Switching such a switch group comprises four contact pad.

with reversing switch management

Widespread variant circuit solutions for homes: N, L - home network; RK - electrical box; A1 - light group; PV1, PV2 - communicating switches; PRK - Cross Switch (+)

Device cross switching the lines is an additional circuit element, which also assumed assembling two feedthrough switches.

They use simple one-button devices.

The operating principle of the triple scheme is as follows:

  1. At terminal «common» PV1 connected phase.
  2. Of changeover contacts are connected terminals 1 and 2 are cross-contact switch.
  3. 3 and 4 of the terminal cross-switch connection terminals 1 and 2 changeover contacts PV2.
  4. Common terminal «common» PV2 is connected to one terminal of the light group.
  5. The second terminal of the light band is switched from the electric zero.

Such decisions involving just a simple one-button devices are recommended for locations where the number of I / O is the number of control places.

Passage room three doors

The implementation of the schematic of Figure 6 in the "natural" form. It would look like by mounting indoors, where necessary the control system of the three places

For example, to create a similar scheme under conditions of passing a long corridor, 1 input and 1 output, switched in the central zone, it is clearly impractical. Obviously, it makes no sense to turn off the light when a person has passed only the first half of the corridor. Meanwhile, the network can meet these recommendations "professional" electricians.

Scheme management from more than three places

The number of control places, in principle, not limited. Another question - how complex are obtained such decisions. The more devices involved in the implementation of the management system, the more difficult it turns out the construction of the scheme.

Increases the number of dial-up lines, the terminals. Accordingly, the increasing costs of component parts and assembly. However, projects in the 4-5 control points are used actively. For example, such a project:

Management of four places

Circuitry for projects requiring an increase in the number of more than three control areas. In this case, an option on four control points (+)

It uses a pair of one-button simple switches the flow of action and a pair of switches that function reversing switch. The diagram shows only one light band. Meanwhile, there is a possibility of connection of additional lighting groups.

Additional lighting group

Additional light sources (light band) may at free rasklyuchatsya terminals and performing light sources intermediate transition zones. That is, in the same long corridors it is possible to use the scheme to a larger number of control places.

five places Management

Five-point light control circuit switching system: P1 - light group; N, L - chain; On 1 On 2 - communicating switches; On 3 On 4 On 5 - reversing switches (+)

In this case, the light should be divided into groups of coverage - front, intermediate, output. With this solution, already actually go a long corridor to the half way, turn off the lights on the passed half and turn on the lights in the area of ​​the remaining half.

Multi-element circuit, of course, not very applicable for residential private sector, since such projects are rarely long corridors or rooms large area on several doors. But for the commercial sphere or the industrial environment such decisions demand.

device management system principles

Installation features to install walk-through switches, in general, does not exist. All work related to the installation are carried out in the standard version, according to the rules of installation of conventional switching devices.

Installation rules Installation of devices

Classical detailing installation for the wiring inside the walls. Fits (tightly walled) Escutcheon. Inside Escutcheon output electric cable. Connects the control device (two keys)

If the budget allows, it is desirable to equip each individual device junction box. Then you need to get a small box in the number of magnitude-mounted switches. But also it can not be excluded with a single RC.

selection factors are directly related to the specific installation conditions. Normally, put the switch "flush" the surface of the walls - internal wiring diagram.

Meanwhile, the realization of projects for private properties (country) often runs with circuits device "Surface" (surface) mount, despite the fact that this approach is considered hidebound themselves.

For the first case will be required for the installation of Enclosures. For the second - false plates. These accessories are required to secure the switch in the niches of the wall panels or directly on the walls.

Connecting the cable to the switch

Cable rasklyuchenny strictly according to the scheme indicated on the back of the device. The circuit layout is simple one-button switch. However mismatch conductors at the wrong face divorce failure of the device

Electrical conductor, usually act trohzhilnye cables where the two conductors needed to power the system, and a third is used as a protective earth formation circuit.

Household lamps can be used without a "ground", if a non-metallic housing. Industrial lamps must have a grounding bus.

Of course, regardless of the destination, domestic or industrial-mounted network is always connected through the additional protection - circuit breaker. This instrument required power calculated by the current cutoff, and with reference to the constructed light passage control system.

The emergence and implementation of this kind of devices in electrical networks may not be as important, but still reflected in the convenience of operation. Moreover, solutions based on the feedthrough of switches actually lead to energy savings.

Meanwhile, improving the equipment does not stop. Periodically, there are new developments, for example, like the touch switches.
