ABSTRACT:
An electrical control arrangement for a curtain assembly has a reversible electric, preferably DC, drive motor, drive devices for connecting the motor to one or more curtains for movement of the curtains in opening and closing directions in response to rotation of the motor in respective opposite directions, and a control device for the motor. The control device includes first, user-operable, preferably remotely-operable, switch device for selecting opening and closing directions of curtain movement, and second switch device positionable for operation by a curtain upon reaching a limit position of its movement in an opening and/or a closing direction. The first and second switch devices are arranged such that the first switch device, when actuated to move the curtain(s) in a first direction, causes energization of the motor to cause it to rotate in a first direction until actuation of the second switch at the limit position, whereupon the second switch device de-energizes the motor and adopts a condition to cause rotation of the motor in the opposite direction when the first switch device is next actuated for movement of the curtain(s) in the second, opposite direction.
