ABSTRACT:
A thermal fuse includes a first electrical contact extending through and engaged in electrical contact with a second contact. A spring is compressed between the first and second contacts. A thermally deformable pin retains the second contact against the compressed spring. The pin is responsive to a high temperature condition such that the pin deforms, thereby allowing the spring to disengage the first and second contacts.
