Abstract
A thermal fuse is disclosed in which a non-resettable bimetal snap disc operates with snap action to open the switch. The body assembly is provided by a unitary cup shaped molded body and a metallic disc cup which cooperate to enclose the switch cavity. The terminal and switch contact means are mounted on lateral projections and extend through adjacent openings into the switch cavity. A bumper extends between the disc and the movable contact to operate the switch in response to snap movement of the disc. The bumper is guided in opposed channels formed in the side of the body so that it is not necessary to provide an apertured wall or shield between the disc and the switch. Means are provided to allow resetting of the device after test operation during manufacture, but such mans are not available for user resetting of the device.
