Abstract
Door curtains with position sensor switches are disclosed. An example door for selectively blocking and unblocking a passageway includes a frame to be adjacent the passageway. The example door includes a curtain moveable selectively to a closed position and a first open position, where the curtain blocks the passageway in the closed position, and the curtain unblocks the passageway in the first open position. The example door also includes a bracket to be attached to the frame. The bracket is movable selectively to a normal position and a displaced position relative to the frame. The example door further includes a switch to be attached to the bracket and in sensing relationship with the curtain. The curtain supports at least some weight of the bracket when the bracket is in the displaced position. The curtain supports no weight of the bracket when the bracket is in the normal position.
