The neutral line inside the switch is straight through and has nothing to do with the switch components. Therefore, if the switch jumps the air switch, the insulation layer of the neutral line through the switch is damaged. The damaged section can be cut off and rewired. It may also be a short circuit in the foot of the indicator light, rewire it.
