Schneider Electric XB2BA31C Push Button Switch

The XB2BA31C is a green, 22 mm complete push-button unit from Schneider Electric’s Harmony XB2 family. With a metal body and flush panel mounting, it accepts a Ø22 mm cutout and uses a spring-return mechanism for momentary actuation. This unmarked device provides a single normally open (1NO) contact configuration (SPST), making it suitable for panel-mounted control circuits where a momentary signal is required to initiate a function. The green actuator offers a clear visual cue of interaction on a busy control panel, helping operators distinguish this button from other controls. As a complete push-button head, XB2BA31C is designed for durable, everyday operation in industrial environments and pairs with other Harmony XB2 components to build compact, modular control stations. Typical applications include start/stop controls and momentary signaling in machines, conveyors, and packaging lines where a compact, robust switch is needed without illumination or additional features. This model is listed as XB2BA31C and is part of Schneider Electric’s 22 mm push-button line, providing a standardized footprint and reliable actuation across the XB2 series.
