Abstract
An actuator includes a solenoid including a coil and a plunger, a switch circuit coupled to the coil, and a control circuit coupled to the switch circuit. The control circuit is configured to receive a feedback signal representative of a plunger position. The control circuit is also configured to provide power to the solenoid via the switch circuit and reduce power to the solenoid via the switch circuit in response to the feedback signal being representative of the plunger being in a full travel position.
