Cable pull switches for hazardous locations are sealed and suitable for environments where the possibility of explosion or fire from flammable gases, vapors, or liquids, ignitable fibers or particles, or combustible dust may exist under normal and abnormal conditions. They have location ratings that classify their suitable operating environment and must be paired with similarly rated devices to be compliant with safety standards. Also known as conveyor control switches, they are installed along conveyors and moving machinery and have tensioned cables that operators pull to quickly turn off power in an emergency.
