Abstract: A pushbutton-operated circuit breaker has a thermal release and an independent trip which can be mannually operated to trip the circuit breaker from the "on" position to the "off" position by depressing the pushbutton. A slide is provided within the switch which, when contacted by the pushbutton, forces a bimetallic spring to bend and release the switch. The slide is movable within the switch such that it is outside of the path of movement of the pushbutton when the circuit breaker is being switched from the "off" to the "on" position, but is engageable by the pushbutton when in the "on" position.
