The  pull  cord  switch  is  a  protection  device  for emergency stop of the conveyor in case of an accident Pull cord switches are installed on both sides of the belt conveyor, which are connected together with steel wires along both sides of the conveyor with the switch gap  no  more  than 50m.  In  case  of  emergency, emergency stop of the conveyor  is supported in any position

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

The pull cord 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.


● The angle shown in the diagram is the inclination action angle of the switch

● Terminals 1 and 2 are normally open with the inclination angle of 20°

● Terminals 4 and 5 are normally closed with the inclination angle of 20°

● The manual reset type is locked by the fixing lever when the lever is inclined to 30° Operation of the reset lever will restore to the original position

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








● Rigid cast-aluminum shell and electrostatic anti-corrosion coating, suitable for installation in harsh industrial environment.

● The protection standard IP67 also to be used in harsh environment

● Excellent durability with high performance micro switches and ball bearings requiring no maintenance.

● Large action travel, high sensitivity, good resetting effect with the rotary cam structure, without dead locking.

● Attached action lever and automatic reset products to be produced.
