    Abstract: A protective device for air conditioners includes a dialectric housing having a pair of terminals separately mounted therein. A metal connector plate is also mounted within the housing and is tempered so as to bend when exposed to a predetermined temperature from a normal position wherein it engages both of the terminals and completes the electric connection therebetween to an open circuit position wherein it is free from electrical contact with at least one of the terminals. At least one catch is provided on the housing and is adapted for retentively engaging and holding the connector plate in its open circuit position in response to movement of the connector plate to this position. The catch is movable out of retentive engagement with the connector plate, but is urged into retentive engagement by a spring. A reset mechanism is connected to the catch and is adapted to urge the catch out of retentive engagement with the connector plate in response to manual manipulation. The protective device includes means for mounting it upon the casing surrounding an air conditioner compressor and electric motor, and is adapted to sense the heat emanating from the compressor and motor. The terminals of the protective device are connected in series with a power source and the electric motor so that upon sensing a predetermined temperature the protective device breaks the circuit between the power source and the electric motor.

    Abstract: A structurally simple low cost manual reset thermostat is disclosed. The thermostat includes a one piece body and two terminal assemblies. The rivet of one terminal assembly connects the switch arm and a reset retainer. The switch arm retains a snap disc in its assembled position. Four guide projections with two on each side of the spring arm laterally locate the snap disc. A reset member is positioned by the guide projections and is arranged to engage the snap disc on opposite sides of the spring arm. Stops are provided to prevent overstressing of the disc by the reset member.
