Square D by Schneider Electric 9001-KP12 Pilot Light

The Square D by Schneider Electric 9001-KP12 Pilot Light is a Harmony 9001-series panel-mount indicator that provides a visual status signal on electrical control panels. Designed for use with 30 mm Harmony 9001 push-button, selector switch, and cover-mounted control unit assemblies, it installs in standard 30 mm panel cutouts to accompany other operator components. Voltage, color, and lens options vary by suffix within the 9001-KP family; for example, related SKUs include 9001KP1G31 (green, 120 VAC) and 9001KT35G31 (24–28 V AC/DC), so you should verify the exact code on your device to ensure the correct electrical rating. These pilot lights are commonly used for machine start/stop signaling and status indication in control panels, and they can be installed with cover-mounted control unit kits in enclosures such as NEMA 1, 3R, 4, or 12.
