Hazardous Location 30 mm Panel-Mount Push-Button Switches
Actuate these switches with a quick push. A housing seals in anything that could ignite flammable material, so you can use them where ignitable gas and dust may be present. You’ll know they’re safe because they meet NEC Class I Div. 2, Groups B, C, D for hazardous locations. Install them in a standard panel cutout.
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 to replace the included contact block.

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.
