Belt conveyor safety cable pull switches are designed for providing a switching system to isolate the power to conveyor system and other equivalent process equipment in the emergency condition. The cable pull switches are actuated by a plastic coated steel wire, which are placed along-side the conveyor. When you pull on the cable at any point, it will trip and automatically lock the switches, deenergizing the conveyor starter contactor. Each switch is bi-directional in operation and has two cable fitted to it from opposite directions terminated with a spring at the anchor points, please see drawing 4 the springs will operate the switch on cable breakage. After tripping the mechanical latch can be released only on the switch itself by the reset lever.
