What is an auxiliary switch?
What will be an ideal response?
Some circuit breakers contain an auxiliary switch. The auxiliary switch is a small micro-limit switch. Its contacts are controlled by the action of the circuit breaker. The auxiliary switch generally contains a set of normally open and normally closed contacts connected to a common terminal. When the circuit breaker is turned on, or closed, the auxiliary switch contacts will change position. The normally closed contact will open and the normally open contact will close. Auxiliary switch contacts can be used for a variety of purposes. In some instances, if the circuit breaker should open, it may be desirable to disconnect power to some other control device on a different circuit. In another application, if the breaker should open, the auxiliary contacts may be used to illuminate an indicator light on the operator's panelboard.
