As we all know, household electricity generally needs a live wire, and the neutral wire and the ground wire are safe. The ground wire adopts a yellow-green two-color wire. When wiring, first use a test pen to find the live wire and the neutral wire, and mark them with colors.

A switch on the wall is used to operate the power supply to the outlet. Wiring method: First connect the wire to the l terminal of the switch, then connect the l 1 terminal of the switch to the l terminal of the two-hole socket, then connect the neutral wire to the n terminal of the socket, and that's it.

B socket without switch manipulation, but manipulation lighting, wiring method: L terminal live wire into the switch, terminal L1 and the base terminal of the switch are coupled to, neutral access to the base terminal of the other terminal, switch and light to form a ring . The live wire L, then the two-pin plug of the access terminal, ends at the neutral point N to the socket, the socket hole becomes the other two circuits.

1. Pay attention to operating the switch socket to install a position. The placement of the switch can be decided according to the living and learning habits of family members. Most people are right-handed, so we opened the door to the right and the switch was on the left side of the door. Others, for two floors of stairs, use dual-control switches on both sides of the living room at the same time.

2. Sofas and balconies are reserved for plug-in interfaces. In the case of an uncertain number, more sockets can be set, more retaining the appearance is better than not enough sockets.

3. Pay attention to operating the switch socket for waterproof and moisture-proof. The socket installed in the bathroom needs to be equipped with a switch and indicator light. If it is installed in a wet location, a waterproof cover can be installed on the surface to prevent water vapor from entering the socket and causing a short circuit.

4. Connection of multi-connection switches: When connecting multi-connected switches, there must be a logical standard, or according to the order of the lights, the lights are getting farther and farther away. Secondly, the exhaust switch of the kitchen should be connected to the multi-connector switch, and the latter one should be placed, and the switch of the control light should not be turned off, so that the functions are separated, and it is easy to remember when it is turned on later. Otherwise, in order to find this light, all the switches are turned on again, which is too troublesome.

5. Some sockets with switches can be set up. The power supply can be cut off without pulling the plug, and it will not affect the appearance. For example, the socket of the washing machine can be closed when not in use, and the socket of the air conditioner can be closed or unplugged during the off-season.
