The  belt  sway  switch  is  a  protection  device  for detecting the belt sway, giving an alarm and trigging emergency stop automatically during the running process of the belt conveyor.

The use of the belt sway switch can prevent damage to the expensive belt to avoid further industrial accidents and personal injury.

The belt sway switch is an indispensable protection device for safe operation of the conveying system, which is widely used in iron and steel plants, fire power plants, cement plants, chemical plants, ports, etc.


■ Action Description

● The angle shown in the diagram is the inclination angle of the side roller

● Terminals 1 and 2 are closed with the inclination angle of 20 degrees and open when it recovers to 18 degrees

● Terminals 4 and 5 are open with the inclination angle of 35 degrees and closed when it recovers to 33 degrees

● The action position of the terminal can be changed according to the adjusting cam
