Fault problem

The boat-shaped switch, the kind of red light that is very common when it is turned on. Sometimes it can’t be turned off, just can’t bounce back, and often break the air switch failure

Solution to the fault:

There is a metal sheet inside the boat-shaped switch, with a spring fulcrum in the middle, spring displacement and aging deformation of the plastic bracket, the switch is not flexible, you can disassemble it after power off to see if it is not damaged by the plastic parts, maybe it can be restored. The neutral line inside the switch is straight through and has nothing to do with the switch parts. Therefore, if the switch jumps to the air switch, the insulation layer of the neutral line of the switch is damaged. You can cut off the damaged section and rewire, pay attention to the insulation to ensure . It may also be that there is a short circuit in the foot of the indicator light, just rewire.
