Introduction
● The pull switch is a protection device that can stop the conveyor emergency when an accident occurs in the belt conveyor. 

● The pull switch is used for emergency stop of the belt conveyor. One end of the steel cable is fixed on a fixed bolt, and the other end is fixed on the switch arm. The distance from the switch to the fixed end is usually less than 34 meters. The distance between the two switches is usually not More than 48 meters (36 meters), there is a support bracket for every 3 meters of cable. The upward or downward force causes the boom to rotate to the alarm position, triggers the microswitch and locks until manual manual reset.


● The standard pull switch has IP65 protection and is suitable for indoor and outdoor installation. The surface can be used in acid, alkali and salt areas after special treatment.Shot blasting surfaces are used for highly corrosive areas.

• I. Overview
     This machine is used for emergency stop when an accident occurs in the belt conveyor.                             
  Second, the working principle
     The switch is two-way touch type, one end is fixed on the pull rope bolt, the other end is fixed on the switch arm, the switch is fixed to a fixed point distance of no more than 25 meters, and the distance between the switches is not more than 30 meters. When the external force causes the switch arm to rotate to the alarm (stop At the position, the micro switch operates.
  Third, the structural characteristics
  ●The switch is a closed, anti-corrosion cast aluminum casing with protection class IP65 . It can be used for a long time under the harsh working environment.
  ●Universal mounting design allows the cable switch to be mounted either on the top of the conveyor stringer or on both sides.
  ●Integral cover plate, so that the switch can be adjusted and maintained without removing the pole.
  ●The imported components are used in the machine, the contact capacity is large, the action is sensitive and reliable.
