DPST/DPST Eyelet Pull Screw Mount Conduit 1000000Cycles The 1CPSA2 Safety Interlock Switch from Honeywell offers emergency stop protection for exposed conveyor lines. The internal mechanism of this Honeywell Switch eliminates unnecessary stops due to temperature variations, overtime cable stretch and other application variables. Safety Interlock Switches are designed for mounting on a door or a cover, so that when the door or other part is opened, they open automatically. These 1CPSA2 safety switches are generally used in conveyor systems that experience wide temperature swings and high-amount of vibration, as well as in perimeter guarding where hosedown conditions are present. They prevent the gear shift lever from moving until the brake is applied. Featuring Silver contact material, this Safety Interlock Switch delivers superior performance.
