Abstract

For reducing the click rate and improving the setting accuracy, in the case of a power control unit (11) for electric heating appliances, a contact separation (D) of two contacts (14, 15) can be varied independently of a position change of an appliance switch (12) with a snap-action element (16). Preferably, the position of the counterstop (33) is modified by an application thereof to a separation cam disk (36). The appliance switch position is fixed by means of a power cam disk (28) and determines the power level. In this way it is possible to randomly set within wide limits the click rite for each setting of the relative on period.
