THERMOSTAT HAVING IMPROVED TEMPERATURE DRIFT CONTROL MEANS

A thermostat is disclosed comprising a support and a thermally responsive bimetallic member having a peripheral section adjacent the support and a central section adapted for movement with respect to the peripheral section in response to temperature changes of the bimetallic member. First and second switch contacts are mounted for relative movement between switch contact open and switch contact closed positions. A spring is provided biasing one of the contacts. An actuating plunger is mounted between the bimetallic member and the spring for movement in response to movement of the bimetallic central section. Temperature drift control means are also provided which means include an energy absorbent dampener disposed between the bimetallic member peripheral section and the support.
