摘要

Described herein is a compliant plunger for a latching solenoid. The compliant plunger prevents disengagement of the solenoid when the solenoid is subjected to incidental axial movement. The compliant plunger takes advantage of a compressible compliance device to absorb the incidental axial movement.
