These Switches are designed for Man and Machine Safety, to avoid accidents, and for stopping the Machine in case of Emergency. In Belt Conveyors, belt swaying occurs due to uneven loading, misalignment of the idlers & due to worn surfaces. Belt Sway Switches are useful to restrict belt sway within the tolerable limits. Belt Sway Switch is mounted on both sides of belt conveyors preferably every 15 to 20 meters.
