The KILLARK hazardous location controls are explosion-proof control devices available in single or double pushbutton, maintained pushbutton, keyed and non-keyed selector switch, single and double pilot light and pilot light/pushbutton styles.
The factory-sealed control device cover assemblies feature a sealing plate between the arcing device and junction box, eliminating 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.
The unsealed control device cover assemblies feature cast copper-free aluminum alloy bodies and covers, open space between gangs for easy wiring from one cover to another, and an internal ground screw; a ground flange joint between the bolted cover and box provide the required flame path.
