There are several ways to wire a dual control switch wiring diagrams

Dual-control switch there are 5 ways to wire:

1, the most common dual-control connection, the public *** end (the public *** end of the marking for the L or COM) connected to the firewire or lamp line (two switches, one connected to the firewire and one connected to the lamp line), and then connect the remaining two terminal blocks to each other. When wiring, you can connect the L1 terminals of the two switches together and the L2 terminals together. You can also connect the L1 and L2 terminals of the two switches to each other.

2, a more special dual-control connection: the two switches are connected to the public **** end, the fire wire to the switch L1 or L2, the light wire to the remaining a terminal.

3, dual-control connection, is the two switches of the public **** end of the lamp line, the two switches of the L1 and L2 of a zero line a connection to the fire line - zero fire line all into the switch. This connection has a problem, that is, when the two switches at the same time open to the firewire, the lamp still exists at both ends of the voltage. At this point, the lamp may emit a faint light or flicker. If someone to the lamp construction, and may cause injury to the construction workers.

4, very common use, dual-control switch to do single-control with: dual-control switch can be used instead of a single-control switch function, which is the most common application in the single-open five-hole socket. Connection is L1 or L2 empty out a, the remaining two terminals a connection to the fire wire a connection to the lamp line can be.

5, dual-control switch to control two lights: a light when the light B lights out, B lights when the light A lights out - two lights, there is always a light is on.

This connection is often used in the industrial side of the indicator, for two circuits of power on and off to remind.
