How is the double switch?

No device is not properly connected, without first studying its "stuffing" and principle of operation. In this sense, the switches do not represent particular complexity.

Device models dvuhklavishnyh repeats odnoklavishnikov structure, but different number of terminals and the principle of connection. External difference is reflected in the model name - it has two separate buttons, each of which controls the electrical circuit.

Apparatus double switch

The switch can be divided into two parts: internal and external. The first consists of a decorative frame keys and - primary light source control tool. They both protect the operating elements. Second - this is the internal mechanism of the terminals

In the manufacture of devices used metal and plastic parts. In particular, the contacts are used for conductive metal - steel and copper.

To better see the individual elements of the switch, we shall understand how the disassembly and connection.

Decorative part - frame and keys

Most often, external parts are made of plastic - safe material that does not conduct electricity. When dismantling or demolition are removed first, and the installation are recorded, on the contrary, in the last instance

The inner part of the switch - the mechanism

The mechanism is mounted on a metal frame and is a volumetric module with several terminals, and sometimes buttons. The top panel affixed markings indicating the ability to connect various wires

Locking tabs or screws

If the mechanism is podrozetnik, then fastening is usually used or spacer tabs located on both sides, or special openings which when installed allows you to align the body instrument

Contacts of the connection diagrams

The main elements of the mechanism - contacts that serve for fixing the wires. On the one hand connect the appropriate wires on the other - the exhaust. Contacts are self-locking, force due to the springs, and screw

Legend, which uses numbers and letters may vary on different models. For example, L may represent a common feed phase, whereas figures 1.2 - exhaust phase. Also to indicate the input-output arrows may be used.

Benefits dvuhklavishnyh models

Worth to abandon the usual and simple one-button devices in the device in favor of a double?

In fact, the advantages are obvious:

  • from a single device can operate in two different lighting fixtures or groups of two lamps;
  • the intensity of light in the room lends itself to adjustment, depending on the number of active light sources;
  • due to selective switching of individual luminaires energy savings occurs;
  • if desired illumination mode can be controlled in two rooms (kitchen and corridor, bathroom and toilet);
  • more rational and economical consumption of electric wires.

Adjusting the light - it is possible to create a comfortable environment to perform certain actions. For example, to work or read, you can use the two buttons to turn on all the lights chandeliers 5-6. And for the rest enough 1-2 bulbs, creating a diffuse, ambient lighting.

Another advantage of the advanced models - different design. Due to the color and the variety of styles you can pick up the device, in appearance the most suitable for decoration.

As odnoklavishniki, dual models are embedded and patch. If the walls in the apartment / house made of brick, concrete, aerated concrete or gypsum board, usually set the internal switches.

Installation of overhead equipment is typical for wooden houses, where when installing internal wiring expect some difficulties related to the standards of the SAE.

Popular schematics

When you select a scheme to connect the double switch, you should consider two related factors:

  • which earthing system used in the house - TN-C or TN-S;
  • one or the two light fixtures controls the switch.

TN-C earthing system considered obsolete. switch mounting feature is that it receives from the switch board only two wires instead of three.

Driving dvuhklavishnika connection

If you connect to the same switch two lamps, it would look like. Note that the neutral wire (blue) combines the earth and zero. Thus, the third wire is not needed

In the houses of the new building uses modern system TN-S. Before you connect your own double switch, you must make sure that from the machine to the site of the power plant will stretch a three-wire cable attachment.

Compare the difference in connecting.

Scheme with three-core wire

The circuit is characterized in that from the electrical junction box stretched three conductors including ground. Accordingly, each lamp / lamp group is also fed land

The presence of a third grounding conductor does not affect the wiring in the switch mechanism: there still remain only the phase conductors, one incoming and two outgoing.

If the lighting controlled with one switch, are located in different buildings, the scheme will be different only breeding conductors in different directions. Consider a design in which one group of lamps is in the room, the second corridor.

The scheme for connecting two groups of lamps

Wiring from the electrical panel and switch, and connection lived in the junction box there is a similar pattern, but more wires in different directions

If the machine is connected a three-conductor wire, the earth is connected to ground luminaire groups and veins as well as zero, bred in the two sides.

Driving chandeliers connection

Connecting the chandeliers two keys single switch simplifies installation only in that instead of the two wires have to pull one - from the switch to the chandelier

The emergence of a third grounding conductor circuit fundamentally does not change: it moves away from the circuit breaker panel and junction box is connected to the ground of the two groups of lamps.

Distribution of a lamp chandeliers groups can occur in different ways, depending on a light intensity requirements. Pyatirozhkovy device can be divided in two ways: 1 + 4, 2 + 3.

The number of connection variants increases shestirozhkovoy chandeliers: 1 + 5, 2 + 4, 3 + 3. That is, the more lamps in the lighting device, the more options for combining them into a group.

Assembly and Installation Instructions

The connection process can last 15 minutes if you want a simple replacement of an old device, or a few days, if there is a need for laying new wiring.

The choice of materials and training tools

If the house / apartment repaired, try to change the old aluminum wiring with copper, which are superior to them in all ways. It is regulated by norms and PUE.

Requirements for the installation site

When choosing a mounting location, do not forget about the recommendations of the EMP: the height from the floor - 60-180 cm, the distance to the pipeline - 50 cm away from the shoal - 15-20 cm

The wires must be laid on the ceiling or horizontally, or vertically downwards - to the installation site. This will prevent accidental cable breakage during subsequent repairs.

For work on electrical installations require hand tools with insulated handles:

  • Universal screwdriver;
  • pliers;
  • pliers;
  • office building or a knife;
  • Screwdriver indicator.

Also suitable marking material and protective gloves with insulation.

Grooving Wall Chasers

If you have to Stroebe wall, pre-need to worry about the presence of wall chaser, punch or drill, and the plaster or mortar for plastering walls

The switch is selected, focusing on interior design. When buying a new cable system into account load. Lighting Group are among the most low-power segments of the network, so it is suitable VVG 1.5 mm² cable, but better VVGng - with plastic protection low flammability.

Counting the cable by means of roulette. The total length of wires must be added the stock to twist in the junction box and installation in terminals. For more information about the cable section of the calculation, see the this material.

About the connection of cables in the junction box

The first stage - the connection cable to the machine, which is in the switchboard:

  • Working living (red. or korich) - into the terminal of the circuit breaker.;
  • null (syn.) - to the neutral bus;
  • grounding (green. or green-yellow.) - to the ground bus.

Works with automatic devices that are on the board, it is advisable to entrust electricians who are responsible for the state of obschedomovoy network. Yourself to make any changes in the switchboard is prohibited. We also recommend you read the article, where we examined in detail the color-coded electrical wires. Read more - go on link.

The shield wire is pulled to the junction box, and from it - to switch and light or two devices / groups. It is important not to confuse wire connection in the junction box.

Compound of wires in the junction box

The conductors are connected as follows: the machine phase + the phase switch part; 2 off-phase circuit breaker to each of two lamps phases; zero with zero guard + 2 lamps; Plot with flap + 2 ground luminaires

As a result, the junction box must perform five compounds. For this purpose, twist, solder, or a more modern method - the terminal box.

Mounting the switch on the wall

switch mount in two ways: in a special box (Escutcheon) or directly into the wall. The second method is preferred when the device is mounted in the plasterboard wall. Consider the basic instructions on how to connect and install a double switch in the home.

Before mounting ET must connect all lights from the operating circuit: a chandelier, a chandelier with a group of spotlights or lamps in different locations. properly test the switch is not possible without the initial installation of fixtures.

Step 1 - cutting and wire stripping

Cut the wires so that they do not take up much space in the recess after the installation of the switch. We release the ends of the cores of the protective layer of about 0.9-10 mm

Step 2 - Connect the incoming phases

Incoming live wire (.. Red, korich) inserted into the corresponding terminal, by contrast, are on the other side terminals for outgoing phases - 2 pieces. fastening screw

Step 3 - phase connection outgoing

We find two terminals for phase conductors onto lamps, insert the stripped wires, anchoring. Exiting phase are usually pink, red, white or brown

Step 4 - Installation of the mechanism on the wall

Check the reliability of fixation lived in the terminals and insert the switch mechanism in the wall or podrozetnik. Is attached to the legs or clamps. Connect the power, check the tester

Step 5 - Check the horizontal position

Check how exactly set the inside of the switch, we can use this level. If necessary, slightly changing the body position

Step 6 - fastening mechanism in the wall

Fasten housing with special mounting screws. The switch must sit firmly, otherwise it may slip out of the recess as a result of active use

Step 7 - Set of decorative frames and keys

At least insert and snap a decorative plastic frame and two keys. The frame should stand still, and the keys, on the contrary, to move freely

Step 8 - testing of the switch

When the switch is fully assembled, once again we check his work, but using the keys. Turn on the machine, press the turn both keys

To further make it easier to determine the work function of each wire, even during installation marked veins.

Do not forget about safety

Any manipulation of electrical installations should begin with a trip the circuit breaker, which is located on obschekvartirnom panel. After that, once again verified the presence of mains voltage indicator with a screwdriver or a tester - and so each time before you start working with wires.

If the shield is located on the landing, at the time the work is recommended to hang a sign with a warning that someone accidentally turned the switch.

Electrical installation work in pairs

If you start to learn the basics of wiring, do not work alone, and be sure to invite your partner for the insurance he and hold the ladder and pliers will give

Protective gloves with insulation can also protect against electrical shock, although they are not very convenient to work with the wires. During shtrobleniya and plastered walls better use of working clothes, comfortable shoes and a mask or respirator to protect the lungs from dust.
