Telemecanique ZB4BW0B45 Push Button Maintained

The Telemecanique ZB4BW0B45 push button maintained is a panel-mount, illuminated control switch in the Harmony XB4 series. It is used in industrial control and signaling systems, commonly installed in machine control panels, conveyors, packaging equipment, and manufacturing lines where maintained operation and visual feedback are required. The device operates at 24 V AC/DC and uses a 1 NO + 1 NC contact configuration, with 22 mm mounting diameter and screw-clamp terminals for reliable wiring. It carries IP66 protection and supports an operating range from -25 °C to +70 °C, making it suitable for demanding environments. The red illumination provides status indication in challenging settings, and the part is compatible with operator stations, production equipment, conveyor controls, and packaging machines that require a maintained push button with illuminated feedback. Common replacements include Schneider Electric ZB4BW0B15, XB4BW34B5, and ZB5AW0B45, reflecting its place in the Telemecanique/Schneider Electric lineup.
