Schneider Electric XB7NW34B2 Harmony XB7 Illuminated Push Button Red 22 mm 24 V AC/DC 1NC Push Button

The Schneider Electric XB7NW34B2 is a Harmony XB7 monolithic illuminated push button with a red lens, combining the pushbutton and its integral LED pilot light in one 22 mm body instead of a separate head and contact block. It is supplied for 24 V AC/DC and switches one normally closed (1 NC) contact on a spring return action, giving panel builders a single-part illuminated momentary control point.

Selection Notes

Because the XB7NW34B2 is a monolithic part, replacing it means swapping the whole unit rather than a head and a contact block separately, unlike the modular XB4/ZB4 series — factor that into spares planning. Pick the 1 NC contact when the button should break a circuit on press (stop, interlock release, reset-to-open logic). For supply selection, the 24 V AC/DC version wires directly to a PLC digital output or 24 V control transformer without an extra signal conditioner. The IP65 front rating holds up against washdown and dust at the operator panel, while the IP20 rear face still needs a sealed enclosure behind it.
