Each of us has repeatedly encountereda situation where you need to cross a dark room to turn on the light, which is very inconvenient. Help here can install a pass-through switch that allows you to control the lighting from two or more places. In some cases, this is not just an additional convenience, but also an urgent need.
We suggest to get acquainted with the peculiarity of the work and the installation of the switch
Why do we need a pass switch?
Проходные выключатели используются для управления lighting devices from different parts of the room (corridor, room, or on flights of stairs). They allow, without returning to the first device, to turn off the lighting from a convenient place.
Most often, such switches on the wall are installed in the following places:
- In the bedrooms. One switch is installed at the entrance to the bedroom, the rest (one or two) near the bed. Entered the room, turned on the lights, got ready for bed, lay down in the bed and turned off the lights.
- На лестницах.Switches can be installed on the first and second floors. From below we turn on the lighting, go up the stairs and turn off the device installed there. If the height of the houses is more than two floors, you can add additional switches.
- In the corridors. One device is installed at the beginning, the other at its end. We go in the room, turn on the lighting, at the end of the corridor - turn off.
This list can be continued for a very long time, since for each case there is its own way of using the system of through switches.
Types of pass-through switches
According to their performance such devices are:
- single key;
- two-key;
- three-key.
The design of the switch determines the number of lighting devices connected to it and places of disconnection. In addition to the control using the keys, there are sensory models.
Device Features
The difference between the pass-through switches and standard devices connected by two wires is as follows:
- In their design provided 3 contact.
- The device allows you to quickly direct the voltage from the first contact to the second or third.
The light turns on when on both devicesthe keys are in the same position. When the position changes, the lighting turns off. Management can be made both from two, and from three and even more points. To do this, connect a cross switch to the circuit, and, if necessary, several.
The single-key device has three terminals.The double switch is equipped with five terminals: one common and 2 each for connecting to the devices. The three-button switch has a more complex device, but if you have a circuit, it is not very difficult to figure it out.
Features of the installation
The installation of a loop-through switch is slightly different from the installation of conventional models, since here instead of two there are three wires. Consider the purpose of each of them.
Two wires serve as jumpers betweenswitches, the third is designed to feed the phase. Before starting the installation of the switch through the switch, it is necessary to purchase a junction box where the wires from all sources of electricity and the necessary tools will be connected.
Tools for work
- Phillips and flat screwdrivers.
- A tool that can be used to remove insulation from wires (for example, a regular knife).
- Passatizhi.
- Indicator screwdriver.
- Level.
- Roulette.
- Punch.
Preparation of niches and gates
To install the passswitch, you must first make the grooves in the wall for laying electrical cables, lay the wires and drag them to the points of placement of the installed devices.
For shtenbing concrete walls it is most convenient to use a punch. Deepening in the limestone partitions is best done with a chisel.
For a brick wall use a perforator notrecommended because the clutch can be split. In this case, the only safe solution is to lay the cables in the seams between the masonry that are previously adapted for this.
Wooden walls are not stitched - wires are laid in special boxes. As a rule, the cable is pulled under the baseboard and output directly under the place where the installation of the switch is carried out.
Sequence of work
- Connect the wires to the switchboard.
- A convenient installation height of the switches is selected. It focuses entirely on personal preferences.
- Strobleniya held. The width and depth of the strobe is 1.5 times larger than the diameter of the wire.
- Stacked in the wire strokes.Elements of the wiring are fixed with small nails. They are driven into the wall in such a way that they support the cable and prevent it from falling out. Before you attach the wire, it should be put in the installation box. After mounting all the switches and checking their operability, the strokes are plastered.
- Holes are made to install switches.
Installation of switches
The wire ends are cut off from insulation.2-3 cm - this is necessary for twisting. In the junction box is twisted wire that supplies power from the shield, with the input contact of the first device. The remaining two output pins are connected to the wires from the other switch. Next, the input contact of the second device with the wire coming from the lighting device is twisted. The zero wire from the lamp connects to the zero that came from the shield. Then all places twist carefully wrapped with electrical tape.
Two light bulb switch
It is advisable to install double-gang pass-through switches in large rooms where you need to control several lighting fixtures.
Their design consists of two singlethe switches located in the general case. Installing a double switch can significantly save on laying a wire to each of the single-key devices.
Such devices are used to turn on the lighting in the toilet and bathroom or on the landing and in the hallway.
The connection of the switch with two keys is as follows:
- In the wall install podrozetniki for appliances. Hole for them is done using a perforator with a crown. Two wires with three wires lead to them through the recesses made in advance in the wall.
- Three-core cable leads to each lighting device: phase, ground and neutral wire.
- Connect the phase wire in the switch boxto the two pins of the first device. To the second device connect the contacts from the lighting. The second wire from the luminaires is switched from zero, coming from the switchboard. When the switching of contacts occurs, the common circuits of the devices are closed and open in pairs in order to switch the specific luminaire on and off.
Circuit Breakers "Legrand"
French industrial company Legrandis one of the leading suppliers of electrical products in the world. Its products enjoy considerable popularity in the Russian market, where a fairly wide range of various series of loop-through switches is provided, such as:
- Valen;
- "Ethics";
- "Galea Life";
- "Mosaic";
- "Kuteo";
- "Celian";
- Cariva;
- Anam;
- "Plekso".
Products of this brand are of high quality, durability and reliability, thanks to which they earned the trust of customers.
The company manufactures products that have differentprice category (from economy class to premium), which allows you to fully satisfy any demand, and many forms and colors of products greatly expands the possibilities of using devices in various interiors.
All Legrand switches through passage havesimilar device devices and connection rules. Their connection is carried out, as a rule, by fastening screws or clips. The company also produces keyboards with fully screw-free switches that greatly facilitate the mounting of copper wires.
For the manufacture of the device manufactureruses ABS plastic or polycarbonate, which gives the switch durability, strength and safety in use. The switch body has anti-moisture and anti-bacterial protection. In addition, it can be made in a different design and have an indicator.
