Killark hazardous location controls are designed for use in environments where flammable gases or vapors, combustible dusts, or easily ignitable fibers or flyings are present. The explosion-proof control devices are available in single or double pushbutton, maintained pushbutton, keyed and non-keyed selector switch, single and double pilot light, and pilot light/pushbutton styles. Factory-sealed control device cover assemblies feature a sealing plate between the arcing device and junction box to eliminate the need for external sealing. Additional features include color-coded wiring, stainless steel captive screws for cover assembly, cast conduit hubs in either dead end or feed-through styles, and single- or two-gang assemblies.
