Title: Thermal switch assembly

Abstract: A thermal switch assembly has a contact member of shape memory alloy sandwiched between a pair of electrically conductive outer members. A contact arm on the contact member has a deformed shape at normal temperatures and a recovered shape at elevated temperatures. The contact arm occupies two different positions in its deformed and recovered shapes, and provides a current path between the outer members in one position while interrupting the current path in the other position.
