    Hi I have a projector screen and the upper limit switch works, you turn it and it moves up or down in the closed position.

    But the switch that regulates the length of the screen does not ? Just wondered what is a limit switch ? and how they work ? and i will try to fathom why it is not working . Thanks

    Would be helpful if you provide details on the Screen and Control Switch you have. - provide a link to the User Guides if possible.

    Hi it was a £100 ebay screen, 110 inch 16.9 with a remote and wall mounted control box. Just wondered in general terms how they worked, mechanically and electrically ?
