Abstract (en)
[origin: US4563667A] For stopping drift or other undesired changes in the response temperatures of a thermal switch using a bimetallic element for driving a moving contact, the design is such that the moving contact and a counter-contact are supported on a common insulating supporting part and the counter-contact is elastically and yieldingly fixed on the supporting part. The lengths of the bimetallic element and of the a strip supporting the counter-contact that may be moved are different to each other so that the two contacts will make contact at different points thereon and with a rubbing effect for clearing oxide and other undesired coatings forming on the said contacts. For producing such a thermal switch with multiple functions, for example the functions of a temperature automatic controller and a thermal protective device, the counter-contact, that is placed so that it may give way elastically, is acted upon by a further bimetallic element.
