- 2 - Abstract Of The Disclosure A bimetallic circuit breaker with a first or main set of movable and stationary contacts. The circuit breaker includes an electrical insulating slide restrained in one position by the movable contact and interposed between the contacts when these contacts are in the open position. The slide is carried by an insulator flame received within a housing of electrical insulating material. The frame is provided with a second or auxiliary set of movable and stationary contacts. The slide is positioned relative to the auxiliary contacts so that it keeps the auxiliary movable contact separated from the corresponding stationary auxiliary contact. When the bimetal flexes sufficiently, the slide is released and the main contacts open, and at such times the slide moves away from the auxiliary movable contact, permitting the auxiliary contacts to close for signalling, at a remote location, the opening of the main contacts.
