ABSTRACT:
An electric hotplate with a thermostat includes a heating plate which is joined to the surrounding cold zones by means of a bridge of relatively thin sheet metal. The actuating device for a thermostatic switch is operated by the vertical movement of the heating plate. This movement arises as a consequence of the horizontal expansions and contractions of the heating plate due to changes in temperature, such movements being converted, by means of the bridge, which acts as a hinge, to vertical movements.
