ABSTRACT:
An auxiliary switch, mounted in a compartment in the molded housing of a circuit breaker separate from the compartment in which the circuit breaker mechanism is mounted, is actuated, when the circuit breaker contacts are open, by cascaded actuating members, one of which engages, through a housing panel dividing the compartments, the latchable cradle of the circuit breaker mechanism to actuate the auxiliary switch when the circuit breaker is tripped, and the second of which is spring biased against a cam surface on an operating member incorporating the circuit breaker handle to actuate the auxiliary switch when the handle is in the off position.
