Another concept is clarified: the switch is connected to the live wire, so there is no live wire at the switch, and there is only the incoming line and the outgoing line!

The lights are aging. The head will be a little red, or there will be wavy lines. The easiest way is to buy a lamp, talk to the lamp seller, and if it's not a problem with the lamp, come over and change the ballast.
It should be that the contact is not bright, you can disassemble the switch board and check it! Fix the wire screws a little! >>>More
Upstairs leakage water distribution is certain, it is recommended not to use the lamp before the treatment of the virtual person pointed out, find the upstairs to negotiate and check, after the treatment (or the building is not sprinkled on the ground), open the lamp mouth to dry (hair dryer) It is best to check the insulation between the lines and continue to use the lamps after installing them.
It can only be a line with light, and that is the line of fire. The other is the zero line, which is impossible to light at all. If the neutral line is on, it is disconnected from the previous line. Measure back along the front zero line, and when you find that the electric pen is lit up, this place is broken!
First of all, check the air opening (leakage-proof electric switch) at home, that is, the circuit switch there, to see if the bathroom and kitchen are a circuit, if it is one, turn on the light first, and then push the air open, to see if it trips, if it trips, it is a circuit problem, on the contrary, it is a problem with the lamp. If it is a problem with lamps and lanterns, then, you go to the lamp market to buy a lamp, go home and prepare tools (pliers, tape, screwdrivers), first turn off the main switch of your home, confirm that it is turned off (your TV lights are not lit), you can replace the lamps, after removing the previous lamps and lanterns, there are two wires on the roof of the shed, you connect these two wires with the two wires of the lamps (after stripping the wires, and then wiring), after connecting, wrap the exposed metal wires with adhesive tape (be sure to wrap them), It is best to make the two wires not next to each other, and then install the lamp, after the finish, turn on the light, push the air open, and the task is completed.
