Comrade, brother. Looks like you're not very good at physics in junior high school. That's basic common sense.
The switch is connected to a wire live wire, and then this wire passes through the switch, which means that this wire is cut off and the switch is connected to two excuses.
I accidentally pulled the safety inside, right? If the key won't open. Unload the glass. Or use a cutter to break the lock.
Does that master know how many wires do you need to lay out for the air conditioner switch? Question addendum: Yes the control switch. 3, but directly connected to the ground connection terminal in the distribution box.
Poor contact leads to an increase in resistance, and the current is converted into heat energy when it passes, so it is recommended to replace the switch, which will have a fire hazard.
