An electro-mechanical actuator is adapted to be connected to an external device for displacing the external device to a predetermined position and maintaining the external device at that position. The actuator includes a housing which holds a drive motor for driving the external device to the predetermined position when the motor is energized and a brake mechanism for maintaining the external device at the predetermined position when the brake mechanism is activated. A switching device generates switching signals for energizing the motor to drive the external device to the predetermined position and for de-energizing the motor and activating the brake mechanism when a predetermined time has passed from a moment the drive motor is energized, to maintain the external device at the predetermined position.
