    Hazardous Location Cable-Pull-Actuator Emergency Stop Switches

    Image of Product. Front orientation. Emergency Stop Switches. Hazardous Location Cable-Pull-Actuator Emergency Stop Switches.
    Safe to use near ignitable gases and dust, the housing on these switches seals in anything that could ignite flammable material. All are UL listed and CSA certified for use in hazardous locations. Yank the cable anywhere along your line to quickly cut power in emergencies. They have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch. Use the tension indicator to visually confirm that they’re reset correctly.
