Schneider Electric XB3-BL42 Push Button 1NC 22mm

Schneider Electric's XB3BL42 push button is a 22 mm, panel-mount, extended red head momentary switch with spring return and one normally closed contact, designed for stop and operator-control functions in industrial automation. It operates up to 500 V AC and 10 A, making it suitable for control panels, machine tools, conveyors, and packaging machinery where a projecting red actuator provides quick, identifiable operator input. This legacy XB3 family device has been discontinued and is superseded by the Harmony XB4 series, with common replacements including Schneider Electric XB4BL42, Schneider Electric XB5BP42, and the Harmony XB4 extended red momentary pushbutton, 1 NC.
