ABSTRACT:
A miniature circuit breaker comprises a housing having a bimetallic element forming a movable contact and connected to one terminal of the circuit breaker and a fixed contact juxtaposed with the movable contact. A slide carries a conductive element adapted to interconnect the two contacts and is shiftable between a position in which an insulating tongue of the slide is interposed between the contacts and a position in which the conductor no longer electrically interconnects the two. A spring biases the slide into the first-mentioned position upon displacement of the bi-metallic element as a result of a current overload.
