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 actua…
