Belt Sway Switch

These switches are designed for the safety of people and machines to avoid accidents and to stop the machine in an emergency.
In belt conveyors, belt sway can result from uneven loading, misalignment of the idler set, and worn surfaces. Belted sway switches are useful to limit belt swings to tolerable limits. It is best to install the belt swing switch every 15 to 20 meters on both sides of the belt conveyor.

Installation method
belt sway switch
1.The deviation switch shall be installed on both sides of the belt conveyor, and the position of the deviation switch should be such that the vertical roller is perpendicular to the belt side plane and the belt side edge is fixed at 1/4-1/3 of the roller in a suitable position.
2.The distance between the vertical roller and the belt should normally be within the natural offset of the belt, plus 50~100 mm.
3.3. The deviation switches are mounted in pairs at the head, tail and intermediate positions. In general, three pairs of tapes having a length of 100 meters are suitable.
4.After the mounting bracket is welded or bolted to the machine frame, tighten the running switch to the mounting bracket with bolts.
