<p>An architectural covering having a drive mechanism for extending and retracting a covering member between opposite first and second end positions. The drive mechanism includes an electric motor unit having a stationary end and a rotating end for rotating a winding core, such as a roller blind shaft, for receiving wound layers of a flexible element, such as a sheet of flexible material thereon. The drive mechanism further includes a motor head, separate from the electric motor unit, providing external electrical control for the motor unit via an electrical interface. A printed circuit board accommodated in the motor head may include at least one of end position limit switches, a switch for setting the first and second end positions, electronic communication means, or a remote control receiver. The electrical interface may include an electrical connector plug, an electrical socket, and/or an electrical cable.</p> |
