Abstract: A number of variations may include a product comprising a latching solenoid comprising: a valve; a spring operatively connected to the valve; a base plate adjacent the valve, wherein the base plate is constructed and arranged to maintain residual magnetism; an armature adjacent the base 10 plate and operatively connected to the spring; a pin disposed within the armature and operatively connected to the valve; wherein the latching solenoid includes a coil, wherein when the latching solenoid is energized the coil pulls the armature in a first direction toward the base plate; and wherein when the latching solenoid is energized the base plate becomes residually 15 magnetized so that when the armature moves in the first direction toward the base plate the armature magnetically latches to the base plate and remains attached to the base plate when the latching solenoid is de-energized.
