A shape memory alloy actuated device is provided for engaging a movable object. The device may include a first movable component, a shape memory alloy for moving the first component from a first position to a second position, a biasing element configured to expand the shape memory alloy object and apply a continual tensile force to the shape memory alloy object. The device may be configured to allow the first component move between the first position and the second position other than by transferring force to the shape memory alloy object. The device may also be configured to allow the shape memory alloy object to expand and contract when the first component is retained in the first position. |
