Schneider Electric ZB4BW7L3741 Push Button

Schneider Electric's Harmony XB4 ZB4BW7L3741 is a 22 mm, panel-mount, metal-front illuminated push-button head that combines a green flush actuator and a red projecting actuator with a central white pilot light. This "without AUXI" variant is a push-button head only, with no auxiliary contacts. The two heads are clearly labeled: the green flush actuator marked I and the red projecting actuator marked O provide immediate visual cues for operator interaction, while the central pilot light supplies status indication. Designed for momentary (spring-return) operation, the assembly is part of the Harmony XB4 family and is intended to be wired into standard 22 mm push-button circuits in industrial control panels. With a robust metal face and color-coded actuators, it offers durable visual signaling and quick identification in demanding environments, making it well suited for start/stop interfaces and other control-panel applications where clear, at-a-glance feedback matters.
