Hazardous Location Foot Switches
These switches are rated for environments where hazardous material is present. Press the pedal with your foot for hands-free operation. They have an oversized guard that accommodates bulky footwear.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Hazardous Location Cable-Pull 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.

Hazardous Location Enclosed Motor Switches
Safely turn motors on and off near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material. Made from aluminum, the housing is lightweight and durable. It guards against water, oil, and other materials that could cause damage. Even in harsh conditions, there’s no need to mount these switches inside an electrical panel.
You need to grip and twist the lever to actuate these switches, so they won’t accidentally turn on or off if something bumps into them. In addition to starting and stopping motors, they work with other circuits, such as lighting and electric heat circuits. They don’t provide overload protection.
