Ways to solve the Rocker Switch KCD4 problem:

The spring displacement and the aging and deformation of the plastic bracket make the switch inflexible. You can take it apart after the power is turned off. If the plastic part is not damaged, it may be restored.

The neutral wire inside the switch is straight through and has nothing to do with the switch components. Therefore, if the switch jumps to the air switch, the insulation layer of the neutral wire of the switch is damaged.

You can cut off the damaged section and reconnect the wiring. Pay attention to the insulation to ensure. It may also be that the indicator pin has a short circuit, just rewire.
