ABSTRACT:
A temperature controller 10 with a bimetallic switching device comprising a bimetallic disk and current-carrying spring disk 22, displaying a first heating resistor assigned to the bi-metallic switching device which has the effect of a self-locking function when the bimetallic switching device is actuated. The bimetallic switching device is assigned a second heating resistor which switches the bimetallic switching device when the current flowing through the temperature controller 10 becomes too high to protect a consumer against excess current. The bimetallic switching device is hereby provided as change-over switch and is connected to both heating resistors 53, 54 in such a way that in each of its switch positions is takes over the current flowing through the temperature 10 controller via a current-carrying part 22.
