The EPS-2XPB-SG-MS explosion-proof momentary switch from Larson Electronics is Class 1, Division 1 and 2, and Class 2, Division 1 and 2 rated for hazardous locations. This start/stop push-button switch is constructed for heavy-duty use and is factory sealed, eliminating the need for added seal fittings and compound. The switch is enclosed in a separate sealing chamber that has smooth, double flanges that mate both to the cover and the mounting enclosure to provide flame-tight joints. Stainless steel hex-head screws attach the sealing chamber to the cover and mounting enclosure to ensure complete sealing. The housing for this explosion-proof switch is made of a malleable iron body with a cast copper-free aluminum alloy cover, epoxy powder-coated for a natural finish.
