Abstract
A temperature switch for limiting the temperature of a glass ceramic plate against the radiation emanating from light and dark radiators has a sensor, which comprises a metallic sensor tube and an inner ceramic rod. Over the sensor is drawn a steatite tube, which on the one hand ensures the electrical insulation between the heaters and the glass ceramic plate and on the other so shields the radiation by reflection, absorption and thermal mass, that the sensor is given a temporary response delay and a greater switching hysteresis.
