ABSTRACT:
An electromagnetic actuator is provided that comprises a housing, a solenoid coil, and an armature. The armature is movably disposed in an interior cavity defined by the housing. Irregular gaps are formed between the armature and the housing to increase the initial force of the actuator and to improve the latching force of the actuator after the actuator has been actuated.
