Abstract
An actuator assembly is disclosed. The actuator assembly includes a driven component, a coil housing including a first coil and a second coil, and an armature housing including a first armature and a second armature. The first armature is axially fixed to the armature housing, and the second armature is slidably received within the armature housing and axially fixed to the driven component. In a first energized state, the first coil is energized, and the driven component is driven a first predetermined distance towards the coil housing. In a second energized state, the first coil and the second coil are energized, and the driven component is driven a second predetermined distance towards the coil housing.
