Abstract: A thermostat for controlling the electrical heating element of an appliance has a user-activated control shaft for controlling the overall operation of the appliance. The thermostat includes a first switch controllable by a temperature sensing element for turning the heating element on and off. When the control shaft is turned to an off position, the shaft disables the operation of the first switch, maintaining it in an open condition. The thermostat also has a second switch which operates a pilot light for indicating when the appliance is on. The second switch is continuously open when the control shaft is in the off position and continuously closed when the control shaft is in an on position.

Abstract: A temperature-sensitive tipswitch includes a pair of normally closed flexible conductive arms. A temperature responsive actuating arm is mounted adjacent the conductive arms and insulation discs separate all three. A bracket is connected into the stack formed by the arms and insulation discs and the bracket mounts a mercury tipswitch. There are one or more terminals extending out from the stack and in electrical contact with one of the conductive arms and a second terminal connected to the tipswitch.
