Hazardous Location 22 mm Panel-Mount Push-Button Switches
A housing seals in anything that could ignite flammable material, so you can use these switches where explosive gas, dust, and fibers may be. They actuate with a quick push. You’ll know they’re safe because they’re UL listed and meet NEC Class I, Division 2, Groups A, B, C, and D for hazardous locations. Install them in a standard panel cutout. The buttons are distinct colors to help you identify switches without reading labels.
Those that are illuminated make switches easier to see in low light.
Switches come with a contact block for each number of circuits they control. Additional contact blocks (sold separately) can be added to control more circuits or replace the included contact block.

Hazardous Location 30 mm Emergency
Stop Panel-Mount Push-Button Switches
Switches immediately cut power with a single push. Use these switches where ignitable gas and dust may be present. Their contact blocks are explosion proof and UL listed for Class I, Division 2, Groups B, C, and D hazardous locations. All are rated NEMA 4X and IP65 for protection from corrosion and washdowns. They include enough contact blocks to control the number of circuits listed.
Additional contact blocks (sold separately) can be added to control more circuits, or replace the included contact block.

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.
