Schneider Electric ZB4BW36B524LED Push Button

Schneider Electric Harmony ZB4BW36B524LED blue illuminated push-button head for 22 mm panel cutouts combines bright LED status indication with a compact round operator. Designed for use with BA9s lamp modules and 24 V operation in complete-unit configurations, this blue head is compatible with the universal LED block used across all colors, delivering consistent brightness and color intensity. The head features robust sealing (IP66, IP69K, IP67) for harsh industrial environments and a spring-return (momentary) actuation suitable for start/stop and signaling functions on machinery. For installation flexibility, Schneider supports multiple termination options—screw-clamp, connector, Faston, or spring-clamp—so it can be paired with a wide range of contact blocks to realize common configurations in control panels. As part of the Harmony XB4/ZB4 modular family, the ZB4BW36B524LED provides a proven blue illuminated operator with long-life LED illumination, offering clear, immediate status indication on equipment while maintaining a compact form factor on dashboards and control consoles.
