12v bussmann circuit breaker issue

[Mudder]

Experiencing some issues of no power via switched breaker. When checked, the switch is not tripped, and can cycle the switch and it works fine for a few days of riding or winch use. Can these things see internal wear/weakness from bumps and 2 years of age?

I would guess the answer is yes. I mean...GFCI outlets go bad, so why not a breaker? I would think anything that transfers juice through a contact is subject to burning/carbon/crud causing interference.
