THERMALLY SENSITIVE ELECTRICAL SWITCH ABSTRACT OF THE DISCLOSURE A thermally sensitive switch has a thermally conductive body within which is a chamber into which extends at least one electrically conductive terminal. Occupying the chamber is an elastomeric body which is expansible and contractile in response to increases and decreases, respectively, in its temperature. The elastomeric body may be normally conductive or normally nonconduc- tive, but in either event is conductive when in its expanded con- dition. When in its expanded, conductive condition, the body engages the terminal and is operable to establish a current path through the body to the terminal. The body may function as an on- off switch or as a rheostat, depending upon the composition of the body.
