Abstract

A thermostat uses a bimetal plate carried by a rotating knob. Adjustment of the knob to select the thermostat's temperature setting displaces the entire bimetal plate towards or away from the electrical switch being activated. The bimetal plate is contained between protrusions from the knob and the coupling to the electrical switch.
