Schneider Electric XALK178 Push Button Station

Schneider Electric’s Harmony XALK178 is a complete control station in the Harmony XALK/XALD family, pairing a yellow plastic housing with a red Ø40 mm mushroom push-button and a twist-release action. Configured with a single normally closed contact (1NC), this XALK178 unit provides a compact Start/Stop interface for panel-mounted automation and is designed to integrate with other Harmony modular components. The yellow lid and red push-button arrangement makes the operator action clearly identifiable on the panel, aiding quick recognition during setup and servicing. This unit is UL and CSA certified, aligning with common North American safety standards for industrial control panels. The XALK178 assembly fits within Schneider Electric’s modular control-station approach, enabling straightforward configuration updates or button swaps without altering surrounding hardware. Typical applications include start/stop and safety-control functions on conveyors, packaging lines, and general machinery in automated environments.
