Abstract
A two-circuit automatic hotplate has a switch, which can be controlled both by a bimetallic strip of a power control device and by an expansion member of a hydraulic temperature sensor. The control heating system of the bimetallic strip is in series with a cooking heating system of the hotplate. The electric power levels of the cooking heating systems are preferably selected in such a way that, wherever possible, a current of the same level flows through the control heating system for the bimetallic strip, so that the same bimetallic strip can always be used.
