ABSTRACT:
A switch comprises a housing which receives a temperature-dependent switching mechanism and has a lower part on whose inner base a first countercontact for the switching mechanism is arranged. Also provided is a cover part, closing off the lower part, on whose inner side a second countercontact for the switching mechanism is provided. The switching mechanism creates, as a function of its temperature, an electrically conductive connection between the two countercontacts, to which contact can be made from outside. The lower part is made of insulating material, and contact can be made from outside with the first countercontact through a wall of the lower part. The cover part is made of electrically conductive material and simultaneously acts as the second countercontact, the cover part being held on an upper rim of the lower part.
