Urgent, urgent, urgent, living room light circuit problem

As soon as the lights in the living room are turned on, they begin to flash, and then the lights in other rooms are darker than usual, and the lights in the living room will be tripped for a period of time, and the lighting lines will trip, and the phenomenon is analyzed: it may be that the lights in the living room are seriously grounded from the switch exit to the line or the lamp, causing the switch to trip in overcurrent, because it is a serious leakage, the voltage is lower than normal, so the lights in other rooms are darker than usual.

Don't be fooled by the illusion, your situation may seem complicated and difficult to understand, but the problem is definitely that the place is not well connected.

You have to use a multimeter all the way to check whether the voltage is stable, so that you can find out the problem. In my experience, the problem lies in the switch that you tripped, because of the bad contact, which caused the heating to trip, not because the current was too large and tripped. You directly check whether the inlet and outlet wires of the switch are loose and heated.

Is there any bad contact in this lamp, try it with another lamp.
