ABSTRACT:
A device for regulating or respectively limiting the temperature provided an electric heating element in cooking apparatus. At least one temperature sensor is provided for regulating or respectively limiting the temperature, the sensor having a rod of high thermal expansion which is disposed in a tube of low thermal expansion, the tube being held between holding elements. A support member adjoins each end of the tube and surrounds the rod. The holding elements are alongside each of the support members. The support member has a coefficient of thermal expansion .alpha..sub.1 which is smaller than a coefficient of thermal expansion .alpha..sub.2 of the adjoining holding element and larger than the coefficient of thermal expansion .alpha..sub.3 of the tube.
