Auxiliary Switch
The Auxiliary Switch provides circuit breaker con-
tact status information by monitoring the position
of the molded cross bar which contains the mov-
ing contact arms. The auxiliary switch is used for
remote indication and interlock system verifica-
tion, and consists of one or two SPDT switches
