Schneider Electric 9001-SK2L1R Pushbutton

Schneider Electric's Harmony 9001SK2L1R is a 30 mm illuminated pushbutton with a red Fresnel cap, a compact operator in the Square D Harmony 9001SK family. The plastic, projecting head is designed for panel mounting in control enclosures and industrial equipment, and the unit is specified for 110–120 V AC at 50–60 Hz. The red Fresnel cap (color code R) provides immediate visual indication in busy control panels, helping operators recognize active circuits at a glance. As an illuminated 30 mm operator within the Harmony series, it integrates into panel-based control architectures where a small, reliable pushbutton with status indication is needed for signaling, start/stop, or function selection in manufacturing, packaging lines, and machine automation environments. Its standard 30 mm footprint and compatibility with the 9001SK accessory ecosystem make field replacements straightforward, maintaining a consistent interface across related Schneider Electric controls.
