Abstract: ELECTROMAGNETIC ACTUATOR MECHANISM A clapper armature is pulled into an operating gap of an electromagnet having three pole faces. Two pole faces extend along a length of the clapper armature. The third pole face opposes a major surface of the armature. As the armature is initially pulled into the gap by the magnetic flux extending between the two pole faces the armature becomes increasingly attracted to the third pole face.
