Abstract
Snap action thermostat has a housing molded onto two flat terminals to form a cavity wherein inner portions of the terminals are exposed. A contact arm is welded to the inner portion of one terminal, a dished bistable bimetal element is placed loosely in the cavity, and a fulcrum plate is provided thereover to bias the bimetal element against the contact arm in one of the stable positions to close the circuit. A mounting plate fixed to the housing provides a heat sink to ensure prompt temperature response.
