Abstract

The switch comprises a control mechanism (13) and a casing (12) accommodating the control mechanism, which includes an electrically conducting lower part (14), as well as an electrically conducting cover part (15). The cover part is electrically isolated from the lower part. The control mechanism produces an electric connection between the cover part and the lower part in dependence on its temperature, and connects the circuit on one hand with the cover part and on the other hand with the lower part. At least one resistance (31, 32, 33, 34) is arranged directly inside the casing, and is connected in a switching position of the control mechanism (13) in series with it between cover part and lower part.
