ABSTRACT:
A thermally-sensitive electrical control is mounted to the head of an electric immersion heater of an electric kettle or like container. The control has an outer periphery of less radial extent than the head so as to be passable, during assembly, through an opening in the wall of the associated container such that the head may be positioned in the opening with the control mounted thereto by insertion of the control through the opening from inside the container. The control includes an electric switch and a snap-action, overheat sensing bimetallic actuator disposed on the side of a body portion of the control which faces the head when the control is mounted thereto and a snap-action steam responsive bimetallic actuator mounted to the opposite side of the body portion. The switch is operated by the bimetallic actuators through an over-center mechanism disposed on the opposite side of the body portion and connected to the switch by a U-shaped link slidbly mounted in the body portion. Terminal pins, adapted to be engaged by a separate socket connector, are disposed on an opposite side of the control body portion. The body portion includes a shelf member which is disposed between and separates the terminals from the steam responsive bimetallic actuator and over-center mechanism.
