Schneider Electric ZB4BH04 Harmony XB4 Push Button Head Metal Red Flush 22 mm Push-Push Push Button

The Schneider Electric ZB4BH04 is a Harmony XB4 red push-button head with a flush chromium-plated metal bezel for a 22 mm cutout, unmarked. It operates on a latching push-push mechanism — one press to engage, a second press to release — and snaps onto a Harmony XB4/ZB4 contact block to form a maintained pushbutton.

Selection Notes

The ZB4BH04's push-push action latches on the first press and releases on the second, so it suits maintained functions (enable, hold, select) rather than momentary ones — use a spring-return ZB4BA head instead where the circuit must open the instant the operator lets go. Choose this non-illuminated version where panel layout or a separate pilot light already shows status, since it carries no lamp and needs no supply wiring of its own.
