Abstract
A control unit () for controlling an electric household appliance, e.g. a refrigerator, is connected in series with a positive temperature coefficient (PTC) resistive unit () which, when supplied with electric current, generates sufficient heat to activate a thermally activated actuating element () for selectively turning on/off respective auxiliary switches () of the electric household appliance. The thermally activated actuating element () includes a temperature-deformable element (), e.g. a bimetallic plate, the deformation of which is transmitted by kinematic links () to a camshaft (), the cams () of which cooperate with the auxiliary switches () of the electric household appliance to selectively turn on/off the auxiliary switches ().
