What is a K line 4 Stage Auxiliary Switch?


Auxiliary switches for circuit breakers and switchgear remotely indicate if the circuit breaker is closed or open. They come in 2-switch configurations.

Reconditioning switchgear with K line 4 Stage Auxiliary Switches from our inventory extends the life expectancy of circuit breakers and switchgear depending on the switchgear’s condition. We provide fast repair and reconditioning.
