Telemecanique XB4BA31 Green Flush Pushbutton 22mm

The Telemecanique Harmony XB4BA31 Green Flush Pushbutton is a 22 mm, metal‑front panel switch with a spring‑return (momentary) action and a single normally open contact (1NO) in an unmarked green actuator. It is designed for standard 22 mm panel cutouts and supports multiple wiring options, including screw clamp, connector, Faston, or spring‑terminal connections for flexible installation in control panels. As part of the Harmony XB4 family, the pushbutton features a robust metal bezel and is compatible with a wide range of XB4 contact blocks for general‑purpose or low‑current signaling applications. The XB4BA31 is commonly listed with IP66 protection, making it suitable for use in harsh industrial environments while maintaining a compact, flush‑mounted profile.
