Schneider Electric 9001-KM-1R Push Button Pilot Light

Schneider Electric Harmony 9001-KM-1R is a 30 mm push-button light module that fits standard Ø30 mm cutouts and is designed to illuminate red status behind Harmony 9001K/SK/KX push-button operators. It operates from 110–120 V AC at 50/60 Hz and uses a BA9S incandescent lamp with a 2.4 VA transformer load, delivering a reliable red pilot light in industrial control panels. This light module is specifically intended for use with the Harmony 9001K family of push-buttons, providing visual feedback on machine status or process signals when paired with compatible red light modules or color caps. Installation is straightforward through screw-clamp wiring and secure mounting behind the 30 mm operator, aligning with Schneider Electric’s interlocking accessories and standard panel cutouts. Common applications include industrial control panels where a clear red status indicator is required in heavy-duty environments, such as motor controls and conveyors. The 9001-KM-1R is part of Schneider Electric’s Harmony 9001K line, offering reliable compatibility with 9001K/SK/KX platforms and a proven approach to panel indication with the red illumination option.
