    • A device that generally includes a multistage solenoid having at least a first stage, a second stage and an armature member that travels therebetween. The device also includes a control module connected to the multistage solenoid. The control module detects a position of the armature member relative to at least one of the first stage, the second stage and a combination thereof. The control module adjusts a magnetic field of the at least one of the first stage, the second stage and the combination thereof based on the position of the plunger armature relative thereto.
