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.

Un commutateur comprend un logement qui reçoit un mécanisme de commutation sensible à la température et a une partie inférieure sur la base interne de laquelle est disposé un premier contre-contact pour le mécanisme de commutation. Sur le côté interne d'un couvercle qui ferme la partie intérieure se trouve un deuxième contre-contact pour le mécanisme de commutation. Le mécanisme de commutation crée, en fonction de sa température, une connexion électrique entre les deux contre-contacts, avec lesquels le contact peut s'établir à partir de l'extérieur. La partie inférieure est faite d'un matériau isolant, et l'on peut établir le contact depuis l'extérieur avec le premier contre-contact à travers la paroi de la partie inférieure. Le couvercle est fait d'un matériau conducteur et agit simultanément comme deuxième contre-contact, le couvercle étant retenu sur le rebord de la partie inférieure.
