Schneider Electric 9001-KM35 Push Button Lamp

Schneider Electric's Harmony 9001KM35 is a 30 mm light module designed to be used with the Harmony 9001K, 9001SK, and KX push-button families, serving as the illuminated indicator block inside standard 30 mm control panels. This incandescent lamp version operates on 24 to 28 V AC or DC and is wired via a screw-terminal connection, with a clear bulb visible through the Fresnel lens to give durable, straightforward status indication in industrial enclosures. Replacement lamps for the KM35 are specified as SYL28PSB (Schneider Electric part number 2550105008); historically, GE44 and GE755 lamps are noted as interchangeable in related 30 mm push-button light modules, with GE755 variants offering longer life. In applications ranging from machine control panels to process monitoring, KM35 provides reliable, plug-and-play illumination for 9001K/SK operator interfaces, maintaining compatibility across the Harmony 9001K family while using standard 24-28 V power.
