Abstract

A control instrument is used for the manually continuously adjustable supply of electric power to electric hot plates in the form of individual power pulses. The control instrument contains a switch, operated by a bimetallic member, whose heater is controlled by an electronic circuit and supplies current to the heating means in individual half-waves. An automatic initial cooking device with an electronic timing member is provided which, during the initial cooking phase, reduces the power supply to heater in a predetermined ratio and consequently correspondingly increases the power supplied to the electric hot plate. The automatic initial cooking device is automatically switched on by the control instrument knob. By rotating the control knob beyond a median power limit the automatic initial cooking device is switched off.
