Abstract
A solenoid assembly includes the solenoid armature assembly having a flux tube or magnetic bearing having an opposed first end and a second end. The armature assembly additionally includes an armature having an opposed third end and a fourth end and movable within the flux tube or magnetic bearing along a mutual axis. The fourth end of the armature is slidably movable beyond the second end of the flux tube or magnetic bearing. A top plate facing the fourth end of the armature, the top plate having an opening for slidably receiving the central core. A slot is included in at least one of the flux tube or magnetic bearing, the armature, and the top plate to improve or decrease release time between the movable contacts and the stationary contacts.
