ABSTRACT:
A temperature responsive switching device is provided in which a pair of spaced bimetallic electrical switching arms each are anchored to opposite sides of a mounting block for attachment to the respective power leads of an electrical supply circuit. The free end of the spaced bimetallic arms each contain an electrical contact. A central arm is disposed between the contacts and has a neutral contact mounted thereon such that each of the contacts on the bimetallic arm is biased at room temperature into contact with the central electrical contact. Upon one of the bimetallic arms experiencing a predetermined temperature the circuit is broken by deflection of the bimetallic arm. Upon the switch experiencing a second predetermined but higher temperature, the second bimetallic arm is deflected to open the circuit. In another embodiment, one of the bimetallic arms has the end thereof linked to the central contact by a solder link which upon the switch experiencing the higher predetermined temperature, melts the solder, permitting the arm to open the circuit.
