Abstract
A thermoelectric switch having a current conducting triggering element made from a shape memory alloy exhibiting a two way temperature effect and coupled to a stressing device which exerts a force on the triggering element to thereby determine the switching temperature of the thermoelectric switch. Mechanical switching amplification is actuated by the triggering element to interrupt current flow through the thermoelectric switch.
