Abstract
A mechanism includes a movable member and a reluctance motor having an armature, a coil and two pole pieces, the armature being operably coupled to the movable member. The mechanism also has a first condition in which the reluctance motor is powered and the moveable member engages the pole pieces to magnetically hold the moveable member in a first position and a second condition in which the reluctance motor is unpowered and the moveable member is in a second position disengaged from the pole pieces. With the mechanism in the second position, powering of the reluctance motor causes the armature to rotate to drive the moveable member to the first position.
