Abstract
An electric solenoid embodiment is comprised of a plunger, a solenoid body, a spring, and a magnet. An area of the solenoid body is configured to receive at least a portion of the plunger and electrical windings within the solenoid body substantially surround the area configured to receive at least a portion of the plunger such that an electrical current through the electrical windings applies force to move the plunger out of the solenoid body or to draw it within the solenoid body. The spring adaptively fits within the area configured to receive at least a portion of the plunger and within a portion of the plunger. The spring provides additional force to the plunger when moving out of the solenoid body and the magnet is used to latch the plunger when the plunger is forced to within close proximity of the magnet within the solenoid body.
