Claim 3:
4. The roller blind assembly of claim 1, further comprising a first limit switch and a second limit switch, wherein:
the first limit switch is attached to the frame and positioned adjacent to the elongated track member to be activated by the extension assembly when the extension assembly has been moved along the elongated track member to fully extend the roller blind sheet across the frame, wherein the first limit switch when activated causes the motor to stop moving the extension assembly along the elongated track member; and
the second limit switch is attached to the frame and positioned adjacent to the elongated track member to be activated by the extension assembly when the extension assembly has been moved along the extension track by the roller blind sheet being fully retracted from across the frame, wherein the second limit switch when activated causes the motor to stop moving the tube of the roller tube assembly.
