A circuit breaker in the light control switch protects
the headlamp circuit, thus eliminating one fuse. A
separate circuit breaker protects the power window,
seat and top circuits. On Corvettes the headlamp motor
circuit is also protected by a separate circuit breaker.
Where current load is too heavy, the circuit breaker
rapidly opens and closes, protecting the circuit until
the cause is found and eliminated.
