Abstract:
A thermally actuated switch comprising:a pair of substantially flat conductive plates positioned in a spaced apart relationship to one another;a non-conductive insulator positioned between said pair of plates;an actuator being mounted between said insulator and one of said plates, said actuator including a blade portion of a shape memory metal alloy, said blade portion being in engagement with the other of said plates to provide a current path between said plates when said switch is in a closed position, and whereinsaid blade portion is operable, within a predetermined temperature range, to move out of engagement with the other of said plates to interrupt the current path between said plates and to cause said switch to be in an open position; anda plurality of fasteners integral with said insulator operable to join said plates together with said insulator and said actuator.
