Wiring diagram of double-open single-control switch

First, lead a wire from the live wire end of the power supply, and then connect it to the L end of the switch. Then another wire is led out from the terminal and connected with the second L terminal. Secondly, two wires are led out from two L 1 ports and connected with the live wires of two lamps. Finally, a wire is led out from the zero line ports of the two lamps and connected with the zero line of the power supply.

First switch the panel, turn on the electric pen and check the exposed position of the connector to see if there is electricity in the circuit. If there is electricity, the switch is broken, and a new switch should be replaced. If there is no electricity in the circuit, there is something wrong with the circuit. At this time, you should contact a professional electrician to test and repair.
