Abstract
An electronic trigger assembly for triggering an actuator, the electronic trigger assembly having a trigger member capable of connection to the actuator. The trigger member may be configured for rotation between a first position and a second position and the trigger member may be able to trigger the actuator as the trigger member rotates between the first position and the second position. The trigger member may also include a guide. A shape memory alloy member may be connected to the trigger member and may be received by the guide such that a substantial portion of the shape memory alloy member is disposed in a curvilinear arrangement. The shape memory alloy member may contract when electrified. The shape memory alloy member may be confined by the guide to contract along a path such that the shape memory alloy member exerts torque on the trigger member and causes the trigger member to rotate from the first position to the second position.
