Pull Cord Switch BX5800 Application The Pull Cord Switch is an emergency switch used to stop the belt conveyor instantly when an accident occurs. When an accident occurs or for the normal corrective maintenance, workers can pull cord at any position along with the belt to stop the belt conveyor. It is widely used in various belt conveyor equipment for coal, cement and building materials, mining, electricity, port, metallurgy and chemical industries Feature  Protection Grade is IP67, suitable for use in harsh environments.  Transmission shaft is made of SUS304 materials with precision grinders, which can better maintain the waterproof feature and the saline-alkaline tolerance and the acid corrosion tolerance.  Long service life, high reliability protection switch  Using high-strength fasteners of 12.9 grade and SUS304 fasteners  Using technology leading dual bearing structure to ensure the transmission shaft flexible  Built-in two groups of micro-switches to control Stop and Alarm signals output.  Independent cam, triggering angle of the device can be freely adjusted for the needs at the scene  5 grades of elastic adjustments of the grid to satisfy the need to fine-tune the operating force  Special anti-corrosion requirements can be customized. Operating principle The Pull Cord Switch is installed at the side of belt conveyor along the conveyor. When an accident occurs in the belt conveyor, the worker can stop the belt conveyor at any position with pulling the cord in order to drive the actuating arm rotating. The rotation may put the torsion spring in motion through the tr
