ABSTRACT:
A thermally and manually operable circuit breaker switch has a housing and first and second conductive plates mounted in the housing. This first plate has a first contact. A cantilevered bimetallic blade is mounted on the second plate and has a free end and a second contact. This second contact is mounted on the free end opposite the first contact. The switch also has a push button with a lateral isolating tab slidably mounted together in the housing. A spring is mounted in the housing for outwardly urging the push button and causing the tab to keep apart the first and second contacts. Also, included is a push rod slidably mounted in the housing transverse to the length of the bimetallic blade and aligned with its free end. Thus, depression of the push rod flexes the blade and separates the first and second contacts to allow the tab to keep the contacts apart.
