A non-explosive, electrically initiated, heat-ignitable actuator constructed and arranged in the form of a biased, collapsible dual piston assembly. When the actuator is in the unactuated condition, the dual piston assembly is prevented from collapsing by an electrically triggerable dual shear pin and associated heat-ignitable wire arrangement. The shear pins and their associated wires are composed of a primarily alluminum and palladium bimetallic composition which when ignited produces a violent but non-explosive reaction which rapidly propagates to all portions of the material. The construction of the dual piston assembly is such that ignition of either or both of the shear pins causes the piston assembly to collapse and thereby bring about actuation of the actuator. |
