How to wire the indoor wall switch

Everyone usually needs all kinds of decoration materials when decorating the room, and also needs to install the lines and pipes before decorating the room. In life, everyone needs to use household appliances, which can help them accomplish something more simply and conveniently. In addition to household appliances, lighting is also an essential part. Everyone needs to install a switch on the wall when using lighting equipment. The following small series will introduce how to wire the wall switch in detail for everyone to choose the appropriate method.

How to wire the wall switch?

As we all know, household electricity is usually three lines: live line, zero line and ground line, in which the ground line is generally yellow-green double-color line. When connecting the switch socket, be sure to use the electric probe to find out the live wire and the zero wire first, and then mark it with color. 1. If the wall switch is used to control the power supply of the socket, the connection method is as follows: firstly, connect the L end of the incoming switch (i.e. the live wire inlet), then connect the L 1 end of the switch (i.e. the live wire outlet) with the L end of the two-hole socket (i.e. the live wire inlet), and then connect the zero line to the N end of the socket (i.e. the zero line inlet).

2. If the socket is not controlled by the switch, and the switch only controls the lamp, then the connection method is as follows: connect the live wire to the L end of the switch, connect the L 1 end of the switch to one end of the lamp holder, and connect the zero line to the other end of the lamp holder, so that the switch and the lamp form a loop. Then the live wire is connected to the L end of the two-hole socket, and the zero wire is connected to the N end of the socket, and the two-hole socket becomes another loop.

Precautions for installation of wall switch

Note 1: The switch socket cannot be installed on flammable objects. If flammable materials burn, it will burn the sheath of switch socket, which will lead to the exposure of wire core and the entry of water vapor, which will lead to short circuit and even fire.

Note 2: Wall switch sockets should be equipped with arc extinguishing devices to avoid the danger of fire or explosion caused by combustible gas leakage.

Note 3: There are two types of wall switch sockets: surface mounted and concealed, and the surface mounted shall not be less than 1. 8m, and concealed installation shall not be less than 0. 3m, the socket of the kitchen and bathroom should be higher than the ground 1. 5m, and the air conditioning socket should be higher than 2m.

Note 4: The wiring of switch socket must follow the principle of "live wire enters the switch and zero wire enters the lamp holder", and the socket must be equipped with leakage protection device.

Note 5: It is best to install a protective box or baffle on the wall switch socket to prevent short circuit or leakage caused by water or oil infiltration. Especially in families with children, there is a danger of electric shock in order to prevent children from reaching out and touching while playing.

Note 6: The wire connector in the socket is broken and should be replaced in time. It is best not to use bare wire connector instead, which is easy to catch fire.

Note 7: the wall switch socket in the kitchen should not be installed above the cooker, because the high temperature here will lead to overheating and damage of the socket.

Note 8: The working voltage and current of the bulb corresponding to the switch should be consistent with the power of the socket. If they are different, it will lead to temperature rise and fire. Note 9: The switch socket must be installed firmly, and the screws should be tightened to ensure good wire contact. Note 10: Although the number of wall switch sockets is not the better, it is better to reserve as many as possible to make some electrical appliances more convenient to use.

The above is the wiring method of the wall switch introduced by Bian Xiao. I believe that after reading it, you should have a certain understanding of the wiring mode of the wall switch. In Japan, when choosing switches, people try to choose some big brands, because the switches of big brands are not only good in quantity, but also perfect in after-sales service. If there are some quality problems during use, you can contact after-sales service for repair or replacement. I hope Bian Xiao's suggestion can help you know more about Changan B switch.
