I have an electrical question. Very limited knowledge on electrical things.

2 weeks ago my court light switch went out. No light on switch or court lights. I have checked the connections in the back of the switch. My inboat LEDs are tied to this switch using jumpers off court switch wires and are also out. So I know that there is no power coming in...at least I thinks so.

Can someone give me a list of things to check? Is there a circuit breaker that I'm missing just for this switch?

All other boat switches working fine.
