Wiring Diagram and Physical Diagram of Duplex Double Control Switch

Wiring diagram of double-open and double-control switch:

Double control switch, three terminals. Press the incoming line as red and blue line, red as L and blue as N. The incoming line is directly connected to the upper terminal of a double-control switch, the middle terminal is connected to one side of the lamp, and the lower terminal is connected to the red line.

The entrance red line is connected to the upper terminal of another double-control switch, the middle terminal is connected to the other side of the electric lamp, and the lower terminal is connected to the entrance blue line.

Physical map:

Connection mode of double control switch:

1, conductor color of double-control switch: live wire: red; Zero line: blue; Round trip line: green.

2. Wiring of double-control switches: the middle terminal of one double-control switch is connected with the live wire, and then the middle terminal of the other double-control switch is connected with the lamp holder and the return wire, that is, two green wires are used to connect the upper and lower terminals at will; The zero line is directly connected to another contact of the lamp holder, and the connection can be completed.

Double switch characteristics:

1, double control switch and single control switch

Features of single control switch: on and off; Double control switch features: on and off, or on and off.

A single control switch is only used to control the switch function of the lamp in one place; The double control switch can be used as two positions to control the switch function of the lamp respectively.

2. Two way switch

Double switches are divided into double single control and double control:

Double single control-two single control switches are combined to control two lights;

Double control-often used to control one light switch or two light switches from two positions, often used in stairwells.
