1. In addition, the double-control switch is also used to control the lights that need to be forced to light in the emergency lighting circuit. Two ends of a double-control switch are connected with a double power supply, and one end is connected with a lamp, that is, one switch controls one lamp.

If you use the traditional switch, you have to go downstairs to turn off the lights. This trouble can be avoided by using double control switches. In addition, the double control switch is also used to control the lights that need to be forced to light in the emergency lighting circuit. Two ends of a double-control switch are connected with a double power supply, and one end is connected with a lamp, that is, one switch controls one lamp.

Installation method of double-control switch

1 and L 1 are input terminals, and L2 is a normally closed output terminal. L3 is a normally open output terminal. L 1A is the channel input, L2A is the channel normally closed output, and L3A is the channel normally open output; L 1B is channel b input, L2B is channel b normally closed output, and L3B is channel b normally open output. When the three-way switch is used for dual control, it must be combined with one-way or two-way switch, and the three-way switch shall not be used as a dual control switch together with the three-way switch.

2. Connect the wires, tighten the 86 junction box and fix the panel. It is forbidden to connect the switch to the neutral line and the live line at the same time. Before installation, ensure that the load and line are in good condition; If there is no blue background light at all, it means that the line is not connected well and needs to be checked; If a single switch is invalid, it means that one line is not connected well; If the two switches are invalid at the same time, it means that the public line is not connected well, that is, the zero-fire line is not connected well or the load is open; If the background light is on, but the touch doesn't work, you need to cut off the power and turn it on again.
