How to connect the light switch

Work with electricity, as a rule, requiresspecial approach and compliance with security measures. If the upcoming electrical work is rather complicated, it is better to call electricians. But when solving simple problems, for example, such as connecting a light switch, you can manage yourself. The article is about this in detail.

Rules of work with electricity

Before you start working with electricity,you need to de-energize the network to protect yourself. Electricity in the apartment is disconnected by a package in the dashboard or an automatic device located on the floor. When studying the issue of how to connect a switch, when installing the device, a phase must be mandatory, and not a neutral wire must break the contactor. In order to find the phase, you need to use a probe. If the wiring is open (as is often the case in the country), then it is necessary to attach the switch to the insulating material. Suitable for this purpose piece of textolite. With concealed wiring, the switch is placed in a special socket. This operation involves the use of the following tools: a knife, screwdriver, pliers.

Before connecting the switch, you canChoose to replace a new model from a rich assortment of electrical stores. Preliminary it is necessary to take with itself the old device. Using the recommendation of the sellers, you can choose a switch that will perfectly harmonize with the color of the wallpaper and walls.

Setting of a single-key switch

Before setting the switch,think about what it should be: one-button or two-button. Pay attention to the junction box. The one-button switch has six wires. Two - the device itself, two for the lamp (chandeliers or sconces), and two - this is the supply wires. Indicator screwdriver determine the phase voltage, one of which is outgoing, the second - incoming. The wires can be in different colors. To home lighting began to give light, you need to bring three conductors to it. Always the phase is connected through a switch and it must go into a break. This is necessary in the event that you have to change the light bulb, turning off the light switch, you can safely do the whole operation without disconnecting the automatic switchboard at the same time. Further, since it is necessary to connect the switch carefully, it is necessary to connect the wires as follows:

ü The wire coming from the lamp holder and the neutral wire

ü Phase conductor and breaker wire

ü Two cables coming from the light source, which are connected to the breaker and the central contact

All these pairs of wires are connected and covered with insulation.

Installation of a two-button switch

Having dealt with the previous model, you easilycope with how to connect a double switch, especially since the differences, although they do, do not affect the complexity of installing the device. The two-button switch model in the junction box does not have six, but eight wires. Three depart from the device itself, three go for the lamp and two wires - feeding. The last wires require accurate phase detection. For this, an indicator screwdriver is used. Next, connect the wires. The cable from the light source (for example, chandeliers) must be connected to the neutral conductor. Connect the wire of the breaker itself to the phase conductor. Then connect the wires from the chandelier to the wires that remained. Now the connection is complete

Having decided independently to cope with such a task,how to connect the circuit breaker, you must observe the safety precautions necessary for electrical work and carefully study the instructions to the devices. If you do not have confidence that you can do it on your own, it's better to invite a specialist.
