ABSTRACT:
An electronic actuator having an armature movable between the legs of a u-shaped structure of magnetic material and guided by a sleeve of non-magnetic material which is held in place by an annular member of the magnetic material. A permanent magnet is located between the legs and is secured between the magnetic structure and the annular member to form a magnetic path through the parts and to magnetically latch the armature in either of two positions. Electromagnetic coils are mounted on the sleeve on opposite sides of the annular member to selectively drive the armature to either of such positions.
