The switch is the main device designed to control the lighting in the apartment. A few years ago, a triple switch was a rarity in homes, but now it is very popular among the population. There is a huge range of such devices that differ in design and modification. The practicality of its application lies in the possibility of regulating three light sources from one control point. If there is a need for such devices, then you need to know how to properly connect a triple switch.
Applications
Interior designers are increasingly offering to distinguish between light groups. Multi-level ceilings, arches, niches require separate lighting. Modern studio apartments, divided into zones, provide slightly subdued light in the recreation area, bright lighting in the functional area near the computer, bookcase, chairs. In the living area, where there is a TV, a sofa and a dining table, you canuse combined light.
How to connect a triple light switch so that it is convenient to use? It will be appropriate:
- in the corridor to connect to the lighting of three rooms at once - a bathroom, a toilet and a kitchen, if they are close to each other;
- if the room has a multi-track chandelier or combined lighting (main and additional);
- when the ceiling is made in several levels;
- if the long corridor consists of three parts;
- if you want to control the lighting of three rooms from one point.
Pros of using
Why is it advantageous to put a triple switch? How to connect it to get benefits?
- Ergonomic - one device looks better than three.
- Economical cabling - less financial and labor costs.
- The need for one hole in the wall instead of three.
- Economy in energy consumption, since full lighting with all the bulbs is not always required, sometimes you can get by with a part.
Triple switch types
Before you install the switch, you need to decide what function is required from it, based on this, choose the type:
- Regular.
- With a light indicator - serve as a beacon to find the switch or signal which rooms the light is on.
- With a socket - usually used in the corridor near the sanitaryrooms.
- Hidden execution - to place the working part inside the wall.
- Outdoor - to place the case on the wall.
Selection criteria
With all the variety of switches on the market, it is recommended to adhere to certain points:
- Models with self-clamping terminals. Modern convenient way to fix wires in the device.
- No external damage - scratches, cracks, chips.
- Reliable terminals that can hold wires firmly.
- Clear actuation of the keys with a characteristic click, without jamming.
- Availability on the reverse side of the device of the scheme, how to connect a triple switch.
Switch device
The principle of operation of a triple switch is no different from a double and a single one. Pressing the key to the "On" position closes the contact of the lighting circuit, voltage appears on the lighting device, and the light bulb lights up. Switching the key to the "Off" position opens the contact and the light goes out. So on each of the three keys. Switch consists of:
- protective part - keys and frames;
- of the working part - the mechanism for fixing the wires and the body.
Switch connection
According to electrical safety, before working with wires, it is necessary to turn off the voltage by turning off the power switch. Before that, determine the wires with phase and zero using a voltage indicator.
If there is a switchhidden design, then first of all you need to drill a technical hole for the socket with a drill with a special cone nozzle. A socket box is inserted into this opening, for a more durable installation of which an alabaster solution is used.
A copper four-core cable with a core cross section of 1.5 mm is connected to this hole2. It is recommended to process the ends of the wires. First, strip the insulation with a sharp knife or stripper. Then put on them tips corresponding to the terminals on the electrical device, and crimp them with a special hand tool - a crimper. If the crimper is not at hand, you can get by with a soldering iron, twisting the strand fibers with your fingers and irradiating them. The simplest option is to simply insert the stripped ends of the wires into the clamping devices of the triple switch.
How to connect? The first core is connected to the phase in the switchboard on one side and to the common contact in the switch on the other end. Three other wires - to the three terminals of the switch, located opposite the common contact at one end, and each wire to the phase terminal of its lighting device (one of three) from the other end of the cable. This can be seen in the wiring diagram of the triple switch. How to connect, you can see here.
Three neutral wires coming from the lighting fixtures are connected to each other and to the zero coming from the automatic power supply.
There should be eight wires in the junction box - three of them come from the power supply (phase, zero and ground). Zero andgrounding goes further to lighting fixtures, and three phase wires connected to three chandeliers are also connected to three wires that came from a triple switch. How to connect - detailed on the diagram.
In old wiring, the neutral wires were often twisted directly in the switch socket, behind the working device, and not in the junction box. Some electricians still practice this method to do without additional nodes in the circuit. Thus, there is no need to install a box, which is important for preserving the appearance of the room, especially with expensive wall decoration.
Important rule - the switch must always open the phase.
Connecting a switch with a socket
How to connect a triple switch with a socket? The diagram is shown below.
It is distinguished by the presence of another neutral wire coming directly from the power supply and connected directly to the outlet. Such a device is used in the corridor, next to the sanitary facilities where a socket is needed, but it is not advisable to make another technical hole separately for the socket. It is also used when the socket is rarely needed, because the switch is usually mounted high from the floor level, and the electrical connector is just above the baseboard. And how to connect a triple switch with a socket so that it is convenient to use both the connector and the keys? You can choose the optimal height for comfortableoperating the device individually.
The three-key switch is undoubtedly very convenient for controlling the light in the apartment. It is necessary to follow the rules of electrical safety when installing it, that is, before work, turn off the automatic power supply and check the absence of voltage with an indicator. After work, check the connection according to the diagram again and only then apply voltage to the network.
