Schneider Electric 9001K2L1R20 Push Button Illuminated

The Schneider Electric Square D 9001K2L1R20 Illuminated Push Button Head is a 30 mm Harmony K-series operator head with a red mushroom‑style lens and a rugged metal bezel, engineered for panel mounting in a standard 30 mm cutout. Designed as the illuminated component of a complete push‑button assembly, this head uses a built‑in lamp to provide visible indication at 110–120 V AC and offers a spring‑return, projecting action, which helps ensure tactile feedback and repeatable actuation in control panels; it must be paired with a compatible 9001K contact block or operator to form a functional switch. Commonly used in industrial machinery and process equipment for start/stop, signaling, or status indication, the 9001K2L1R20 head integrates with Schneider Electric's Harmony 9001K family to maintain consistent form, color, and mounting compatibility across components, supporting durable operation in demanding environments.
