- Description
The Schneider Electric XB7NW33B1 is a Harmony XB7 illuminated push button for 22 mm panel cutouts, with a green projecting operator that returns by spring and lights through an integral LED supplied at 24 V AC/DC. It switches a 1 NO contact through screw-clamp terminals, and the IP65-rated plastic body suits dusty or washdown-duty control panels.

Selection Notes
The XB7NW33B1's integral LED needs no spare bulb stock and reaches a UL type 12 enclosure rating, a step up from the BA9s incandescent version in the same Harmony XB7 projecting body. Its 24 V AC/DC supply should be matched to whatever control-circuit voltage already feeds the panel — 24 V DC for PLC-fed stations, 230 V AC where line voltage is run directly to the pilot devices.
