Anonymous users2024-01-24There is no need for a neutral line to connect to a dual-control switch, unless there is an indicator light. The dual control switch has three connection points, connect the live wire to the middle point of the "door switch", and connect the remaining two contacts to the two wires to the contacts on both sides of the "living room switch", and connect the bulb to the middle and indirect points. Now the key is that I don't know if you can throw two lines in the environment from "Entrance Switch" to "Living Room Switch", and then throw the live line of the original "Living Room Switch" to "Entrance Switch" to solve it.
You'd better let the professionals do it, don't break it.

The first thing you need to know is the polarity and purpose of each power cord on the wall, which is a prerequisite for proper connection. The switch is two dual-control switches, of which L10, L11, and L12 are a group, and L20, L21, and L22 are a group. The L10 and L20 interfaces are connected to the live wire, and the living room lights used by dual control can be connected according to the dual control, and the spotlights can be connected according to the single control. >>>More
It's normal.
丨ED trace current can glow, there is a short pulse when the power is turned on, and it can be seen when the light is not too bright. >>>More
The switch is replaced with the zero live wire, which is useless, indicating that it is a problem with the power supply, and the power supply zero line provided by the power grid also has a voltage, which is caused by the unreliable grounding of the neutral point of the transformer, so the energy-saving lamp will flash when the light is turned off.
The dual control is just a reverse line, it will not be off, the self-locking switch is pressed, this bounces up, and the principle is not the same thing as the self-locking switch.
It is more convenient to install dual control in the living room, because the light in the living room can be softer when there are no guests at home, and the lights should be brighter and have an atmosphere when guests arrive at home, showing the owner's decoration style and taste.
