Schneider Electric XB4BW33B5 Illuminated Pushbutton

Schneider Electric's Harmony XB4BW33B5 Illuminated Pushbutton is a 22 mm, metal-housing pilot switch with a green flush actuator and a plain LED-lens face. It provides a dual-pole configuration of 1 normally open and 1 normally closed contacts, enabling standard signaling and control circuits in automation panels. The unit is illuminated by a universal LED and is designed to operate from 24 V AC or DC, ensuring visibility in mixed electrical environments. The compact, rugged button is intended for panel mounting on standard 22 mm cutouts and integrates neatly with other Harmony XB4 components to create compact control stations. Use cases include machine start/stop signaling, indicator status for equipment, and basic interlock signaling in industrial systems. The green illumination provides immediate status feedback to operators, even on bright factory floors. As part of Schneider Electric's Harmony XB4 family, XB4BW33B5 supports consistent electrical characteristics across the lineup, helping maintain uniformity in control architectures.
