Dual control requires two triple dual control panel switches (dual control threading is required).

Anonymous users2024-01-21Three double-open two-way seats can be used to tube switches.
Each switch is three wires, and the specific connection method is shown in the following figure
You mean, dual control switches, two switches control one light. The switch with five holes must be a single-open and double-control switch, and the single-open and double-control switch at the door form a double control.
This is the traditional one-light three-control wiring method, but now there is a multi-control switch in remote control mode, no wiring, the control point can be increased at will to change the location, it is very convenient, you can search it on the Internet.
The connection method of the duplex switch, to be connected to the above figure, the connection method upstairs is the old connection, there is considerable danger, such as the switch failure is easy to short circuit, the advantage is that there are few wires, and it can be easily connected to the socket. The biggest defect is that sometimes the firing wire cannot be disconnected in the lamp head, and it is critical for maintenance personnel to repair and replace the safety of the lamp. Therefore, it is no longer taught in the teaching of electricians. >>>More
First of all, there must be pre-installed wires from the position of the switch at the door to the position of the switch at the head of the bed.
