The lights in the living room flicker, they can be turned off but they flicker when they are turned

Here's why: the switch controls the neutral line!

Electrical analysis: the lamp is turned off and is still connected to the live wire, there is also electricity, the live wire will form an electric field, the phosphor in the lamp is discharged, the phosphor close to one end of the live wire is electron in the electric field, and the end away from the live wire is less affected by the electric field and is considered to be not charged, so that the phosphors at both ends of the lamp form a voltage, when the continuous discharge makes the voltage high enough to penetrate the entire lamp, the voltage breaks through the lamp to discharge the lamp and flash, the electrons with the lamp are neutralized, the voltage disappears, and the lamp becomes dark, and proceed to the next charge-discharge cycle, resulting in a flash!

Solution: It's very simple, connect the switch to the live wire! In fact, if you feel that the impact is not big, you can leave it alone, because the power consumed by the flashing of the lamp is not enough to make the meter turn, that is to say, your meter will not run, and it can be lit for free at night!

Your switch does not completely cut off the live wire, your light is grounded at this time, instead of the neutral line, but it is not completely replaced, so it will flash and flash, strange and terrifying, you turn off the power switch tomorrow and connect the live wire to the switch. Hope to adopt.

It should be a short circuit in the line, such as a line problem.

The switch controls another wire, and the two wires are reversed.

Normal, it won't flash for a while.

Swap the live ground wire on the switch oK

This seems to be caused by the fact that the neutral line is not broken.

Let's see if the starter is broken.
