An actuator is provided that uses two lengths of shape memory alloy (SMA)wire to kinematically couple a first and second lever together. The two SMA wires are routed in generally V-shaped paths around a link pin that is coaxial with the first and second levers. By selectively contracting one of the wires, the link pin slides between a locked and an unlocked position. A locking pin extending from the link pin couples the first and second levers together while the link pin is in the unlocked position.
