Schneider Electric ZB4BW563 Push Button Momentary Flush

ZB4BW563 is a blue, 22 mm flush illuminated push-button head for Schneider Electric's Harmony XB4 modular family, designed to work with XB4 operator bodies for a complete push-button assembly. It is a momentary (spring-return) head with universal LED illumination and a clear boot, enabling panel-mount signaling that returns to its resting position after actuation. The head is constructed from metal for durability and features a flush insert to sit level with the panel surface. As part of the Harmony XB4 family, ZB4BW563 is one of several head options offering a blue illuminated flush option suitable for color-coding and quick visual feedback in control panels and automation interfaces.
