摘要： A thermal relay construction capable of operating a pair of electrical contacts. The thermal relay includes an electrical heater of the self-regulating PTC type which is mounted upon and thermally coupled directly to a bimetal snap disc so that heat generated by the heater causes the bimetal snap disc to overcenter and operate the electrical contacts. The other electrical connection to the heater is made through a compensating blade which bears against the heater to compensate for ambient temperature effects on the thermal relay. An electric range oven control uses temperature sensitive electrical contacts in conjunction with the thermal relay to control the oven heaters.

摘要： A combination thermostat tip switch assembly in which a bimetal member carrying a double-faced contact is mounted in a stack assembly between two resilient contact leaves each carrying an electrical contact adapted to mate with the double-faced contact. The stack is mounted on a rigid base member which supports an adjusting mechanism adapted to cooperate with one of the contact leaves so as to provide an adjustment of the operating temperature of the thermostat. A position sensitive mechanism in the form of a pendulum is mounted on one of the contact leaves and cooperates with the other contact leaf to move the two away from one another.
