Abstract: A three position electrically operated actuator has a self centering system so that if power is off for the actuator, it returns to a central position. The actuator comprises a center cavity with a first solenoid on one side and a second solenoid on the other side, a shaft extends through the center cavity and is joined to a first magnetic core of the first solenoid and a second magnetic core for the second solenoid. The shaft has a connection at least at one end for connection to a gearbox or the like. When the first solenoid is energized the shaft moves axially in one position so the connection is at a first position, when the second solenoid is energized, the shaft moves axially in the opposite direction so the connection is at a second position. A coil spring is provided in the cavity, and when neither solenoid is energized the spring moves the shaft so the connection is in a third position midway between the first position and the second position.
