ABSTRACT:
An electric hot plate has an overheating safety switch having a steatite housing which is inserted into the lower sheet cover plate of the hot plate and is supported with two feet on the lower side of the heating elements of the hot plate. A bimetallic member is positioned parallel between these feet which acts on a snap switch positioned in the steatite housing via a transmission rod. The transmission rod is continuously pressed against the snap switch by a plate spring and a guide on the snap switch. As a result of this, it is fixed precisely in its position. The overheating safety switch simultaneously forms the lead-through passages for the electric hot plate connections.
