ABSTRACT:
Actuating device for movable parts, such for closure parts for apertures in vehicles, having a reversible direct current drive motor, a polarity reversing actuating switch in the motor circuit for applying direct current to the motor circuit with a polarization corresponding to the desired motor rotational direction; a relay with a switch contact in the motor circuit which is in series with the polarity reversing switch; and further, having a position responsive switch connected with the relay control circuit for actuating the relay in a reference position of the movable parts, for the purpose of deactivating the drive motor by opening the switch contact. The relay is a direct current relay, which, upon application of a first or second voltage level at its control circuit, closes or, respectively, opens the switch contact. Connected with the relay control circuit, there is an electronic relay actuating stage with a storage capability, with stage, upon closing of the polarity reversing actuating switch in either direction, at least when the movable part is in the reference position, has applied a setting signal to an input thereof, in response to which setting signal the relay actuating stage applied the first voltage level to the relay control circuit, at least until the movable part has left the reference position.
