Rocker switch, the most common one when the red light is on. Sometimes it does n’t turn off, it just does n’t come back, and often jumps to the air switch to solve the problem:

There is a metal piece inside the boat switch with spring fulcrum in the middle, spring displacement and aging and deformation of the plastic bracket, the switch is not flexible, and you can take it apart after power off to see if it is not damaged by the plastic parts. The neutral wire inside the switch is straight and has nothing to do with the switch components. Therefore, if the switch jumps through the air switch, the insulation layer of the zero wire passing through the switch is damaged. The damaged section can be cut and rewired. Pay attention to the insulation. . It may also be that the pin of the indicator light is short-circuited, and you can reconnect it.
