ABSTRACT:
A solenoid includes first and second armatures disposed on either side of a solenoid core. The core includes first and second sets of legs disposed on opposite sides of a central member. A drive circuit provides a first current level to cause flux to flow in a first path through the core and thereby move the first armature without substantially moving the second armature. The drive circuit can provide a second current level greater than the first current level to saturate the first path and thereby redirect flux into a second core path to move the second armature.
