An actuator position control system includes an electronic controller and encoder that control and monitor an actuator's position between its position limits, while mechanically actuated limit switches prevent attempts to exceed the actuator's position limits, even if there is a loss of calibration, software error, or electronic controller failure. When actuated, the limit switches provide position calibrating information to the electronic controller. Embodiments can control linear and/or rotary actuators. The encoder can include intermeshed gears and magnetic Hall-effect position sensors. A mechanically driven position indicator can visually indicate the actuator's position. An electromechanical control system can be included that can transition the actuator between its limits even in the event of electronic controller failure. Embodiments can alert a user if the electronic controller fails.
