PULL CORD SWITCH

Emergency stop rope pull switch for belt conveyors
 

Pull Cord Switch is a switch for emergency stop when an accident occurs around belt conveyors and transportation machinery. Mainly used for belt conveyors that transport raw materials (ore, coal, lime, gravel, etc.) at production sites. Since 1975, it has been a favorite in the field for many years.

*Emergency stop switches are required to be installed on belt conveyors according to occupational safety and health regulations.

Advantages

  3. It is also effective for safety measures before work. If you operate the Pull Cord Switch while working around the conveyor, you will not accidentally start the conveyor. Serious accidents can be avoided.
