How to connect the switch socket?

There are generally three lines for electricity safety, namely, live line, zero line and ground line. The grounding wire is generally yellow-green double-color wire; You can find the fire line with an electric pen, remember the color of the fire line, and it is best to mark it; The rest is usually the zero line. Remember the color of the zero line.

The 1. switch is used to control the on-off of the socket power supply. You can connect the live wire to the L end of the switch (live wire inlet), the L 1 end of the switch (live wire outlet) to the L end of the two-hole socket (live wire outlet), and the zero wire to the N end of the socket (zero wire inlet).

2. The switch is used to control the lamp, and the socket is not controlled by the switch. Wiring method: 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 wire 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.

3. Standard connection mode of socket: There are three connection holes in three hole socket, namely L- live wire, N- zero wire and E- ground wire. Remove about 2 cm of insulation from the wire end to expose the copper wire end. The two wires are twisted together, inserted into the hole, and the screws are tightened. If the thread is too long, cut it off; In order to be safer, you can use an electric pen to determine the fire line. It's usually left and right fire. Connect the fire line on the left, the zero line on the right, and the ground line to E.
