Abstract
The present invention is directed to a rolling protective shutter having an improved stopping mechanism that prevents the shutter from completely rolling up onto the shutter support member, and that is hidden within the shutter housing or the side tracks. The stopping mechanism may include a limit switch operatively connected to a drive motor to detect a disposition of the base slat of the shutter curtain proximate the shutter housing. The limit switch may actuate to turn off the drive motor at an appropriate position to retain the base slat within the side tracks and to prevent damage to the shutter housing due to engagement by the base slat.
