A method for actuating a solenoid can include, when the solenoid is in the unactuated position: (i) providing a control signal at a first voltage level to the solenoid, and (ii) adjusting the control signal to a second voltage level to actuate the solenoid to the actuated position. The first voltage level can be greater than zero but less than a voltage sufficient to switch the solenoid to the actuated position. When the solenoid is in the actuated position, the control signal can be adjusted to a third voltage level (less than the second voltage level and less than a voltage insufficient to maintain the solenoid in the actuated position) to switch the solenoid to the unactuated position. The control signal can be adjusted to the first voltage level after the solenoid has returned to the unactuated position. |
