PRINT PIN ACTUATOR AND METHOD OF MAKING SAME Abstract of the Disclosure The high speed print pin actuator disclosed herein is constructed as two sub-assemblies, a U-shaped fixed magnet structure and an armature sub-assembly. One leg of the U-shaped structure constitutes a coil core and the other includes a permanent magnet and a keeper plate, the ends of the keeper and the core being finished to a common plane. The armature assembly includes a flux return bridge structure which extends from the keeper to a region adjacent the end of the coil core and which is bifurcated to receive an armature which is selectively attracted to the coil core. The armature is carried on a spring which is, in turn, mounted on the bridge structure. With the spring in a deflected position, the armature is finished to a common surface with the portion of the bridge which mates with the magnet structure. Accordingly, assembly of the armature sub-assembly with the U-shaped fixed magnet structure is facilitated and accurate parallelism of the armature and pole piece is provided. Preferably, a thin shim of a wear resistant material is inter- posed between the spring and the bifurcated portion of the bridge structure. -1-
