Abstract (en)
[origin: US4862132A] A bimetal switch 1 has an insulating base 2 on which a contact spring 3 is arranged, this contact spring having at its unattached end 4 a moving contact 5. In its center area 6, the contact spring 3 supports the bimetal element that activates it. A fixed contact 8 that works in conjunction with the moving contact 5 is arranged on the insulating base and the heating resistor is installed beneath the center area 6 of the contact spring 3. In order to develop a bimetal switch of this kind such that it is simpler to produce and at the same time operates more effectively, the heating resistor 9 is configured as a foil resistor that is arranged on that side of the insulating base that faces the contact spring 3 so as to be flat and in thermal contact with the base, this then forming a laminated body with the insulating base 2.
