Appleton EDKB-U2 Indicator Light Module Assembly

Appleton EDKB-U2 Indicator Light Module Assembly is a two-circuit universal pushbutton control station from Appleton’s Contender Series, designed to mount on standard EDS explosion‑protected enclosures and arrive factory sealed for hazardous locations. The U2 designation denotes two universal circuits (start/stop) wired through a single, compact cover assembly that attaches to EDS bodies with four captive stainless bolts. In the Contender catalog, EDKB-U2 is listed explicitly as the 2‑Circuit Universal Start/Stop variant, compatible with NEC/CEC explosion‑protection schemes across Class I, Division 1 and 2, Groups C and D, and Class II, Division 1 and 2, Groups E, F and G (and Class III where noted). Some configurations in the family support pilot lights as part of a combined assembly, including a 6 W, 120 VAC lamp option, enabling a visual status indicator alongside the two pushbuttons. Typical applications include industrial control stations for machinery in oil and gas, chemical processing, mining, and other hazardous environments where a sealed, durable control interface is required.
