Abstract
A solenoid linear actuator comprises a unibody soft magnetic core with a central body and an upper disk and narrower end extrusions, and a pair of soft magnetic bodies on the two ends of the solenoid. When the solenoid is energized, unibody core is magnetized and attracted to the soft magnetic plates from below, pulling unibody core downward. The extrusions on the two ends of unibody core actuate external mechanisms (pushers and cantilevers, respectively) to accomplish various electrical switching operations. A permanent magnet can be added to the upper side to assist the actuation.
