bartamos,
I was looking at the
Jim carter switch that
Lightholder's Dad posted and could not see a replaceable circuit breaker.
Then I saw this
Switch and realized that the box on the back of the switch is the circuit breaker.
If you look at the Jim carter switch that same box is on the back of the his switch.
It is just turned 90 degrees and it is kind of covered buy the circuit board.
There are two electrical connecting post on the circuit breaker, one connects to
the switch's bus bar and the other post accepts the vehicle's battery power.
I Googled
Automotive Auto-Reset Circuit breaker there are quite a few to choose from.
Here is another
Switch that shows the circuit breaker better.
