Abstract
An electro-mechanical system has a solenoid with a plunger received in a housing chamber. A plunger portion extends outwardly of the housing. There is at least one coil, and a control for the at least one coil. The control selectively applies a first higher level current to the coil to move the plunger to an actuated position relative to the housing. The control is operable to stop the supply of first high level current to the at least one coil and allow the plunger to move to an un-actuated position. The control is operable to supply a partial power current to the at least one coil when in said un-actuated position to resist movement of the plunger. A method is also disclosed.
