How to wire the double button switch (one start and one stop)?

1. Before installation, the power supply must be cut off, and it is strictly forbidden to install live, and install it by professionals. Open the packing box, take out the switch, use a screwdriver to reach into the gap at the lower end of the switch, pull it up gently and forcefully, then the panel can be separated. L1 is the input terminal, and L2 is the normally closed output terminal. L3 is the normally open output terminal. L1A is the A channel input, L2A is the A channel normally closed output, L3A is the A channel normally open output; L1B is the B channel input, L2B is the B channel normally closed output, and L3B is the B channel normally open output. When a three-way switch is used as a dual-controller, it must be combined with a single-way or two-way switch, and a three-way switch cannot be used as a dual-control switch with a three-way switch.

2. Connect the wires, fix the 86 junction box with screws, and buckle the panel. It is strictly forbidden to connect the switch to the neutral wire and the live wire at the same time. Before installation, ensure that the load and wiring are intact; if there is no blue background light, it means that the wiring is not connected properly, and the wiring needs to be checked; if a single switch is invalid, it means that one circuit is not connected; if the two switches are invalid at the same time, it means that the public line is not connected. Connected, that is, the zero and live wires are not connected well or the load is open; if the background light is on but the touch does not work, you need to cut off the power and re-energize [2].

USE

In addition, the dual-control switch is also used to control the lamps that need to be ignited forcibly in the emergency lighting circuit. The two ends of the dual-control switch are connected to dual power supplies, and one end is connected to the lamps, that is, one switch controls one lamp.

If you use a traditional switch, you have to run downstairs to turn off the light if you want to turn off the light. Using a dual-control switch can avoid this trouble. In addition, the dual-control switch is also used to control the lamps that need to be ignited forcibly in the emergency lighting circuit. The two ends of the double control switch are connected to dual power supplies, and one end is connected to the lamps, that is, one switch controls one lamp.
