Schneider Electric XB4BW3465 Harmony XB4 Illuminated Red Flush BA9s lt250V 1NO+1NC Push Button

The Schneider Electric XB4BW3465 is a Harmony XB4 illuminated push button with a chromium-plated metal bezel, a red flush head with a plain lens and a BA9s bulb base (bulb not included), supplied at up to 250 V AC/DC. The 1 NO + 1 NC contact block switches through screw-clamp terminals, and the sealed body carries IP66, IP67, IP69 and IP69K protection for a standard 22.5 mm panel cutout.

Selection Notes

The XB4BW3465 combines a push button and a pilot light in one head: the spring return mechanism gives momentary 1 NO + 1 NC switching while the BA9s-lit red lens can run from a separate signal to show machine state, which is why illuminated flush buttons like this one are typically wired as combined start/confirm or stop/fault indicators rather than plain momentary inputs. Because the lamp uses a replaceable BA9s bulb rather than an LED, maintenance teams already stocking BA9s lamps for the XB4BV6x pilot lights can use the same spares here. The flush profile sits closer to the panel face than a projecting head, reducing the risk of accidental actuation, and the IP66/IP67/IP69/IP69K sealing holds up under wash-down.

Applications

Used where a single 22 mm cutout needs to combine a momentary red push button with its own pilot indication, on panels supplied at up to 250 V AC/DC with BA9s lamp stock already on hand.
