Overview
The Square D 9001 SK1L is a 30mm illuminated pushbutton operator part of Schneider Electric’s Harmony® 9001 series. This model features a plastic base with corrosion-resistant construction and full guard protection to prevent accidental actuation. Engineered for heavy-duty industrial applications, the SK1L configuration includes the illuminated operator assembly without a light module, allowing integration with separate lighting solutions per application requirements.
Key Features
- Plastic Base (SK Type): Corrosion-resistant plastic operator body ideal for washdown and outdoor environments
- Full Guard Protection: Protective bezel reduces risk of unintended activation
- Automatic Self-Grounding: Integrated earth connection eliminates additional grounding wires
- Modular Design: Compatible with separate light modules, contact blocks, and color caps for flexible configuration
- Industrial Durability: IP66 and NEMA 4/4X rated for oil-tight, dust-tight, and water-tight operation without additional boots
- Certification: Complies with IEC, UL, CSA, EN, and NOM standards; CE marked and ABS certified

Typical Applications
The 9001 SK1L pushbutton is widely used in:
- Automotive: Assembly line control stations and press controls
- Machine Tool: CNC and conventional lathe operator interfaces
- Crane & Hoist: Pendant and fixed-station controls in harsh environments
- Food & Beverage: Washdown-rated stations requiring corrosion resistance
- Material Handling: Conveyor and sorting system activation
- Petrochemical & Wastewater: Corrosive-atmosphere-rated control panels
- Metallurgy: High-temperature foundry and smelter environments
Compatibility & Replacements
The 9001 SK1L is a drop-in compatible operator within the Harmony® 9001 Series. It pairs with:
- Contact Blocks: 9001KA1 (1NO+1NC), 9001KB1, and other standard 9001-series contact blocks
- Light Modules: 9001KM1 (110/120 VAC transformer-type), for external illumination
- Replacement Operator Heads: Interchangeable color caps and mushroom heads maintain inventory efficiency
- Legacy Alternatives: 9001K operators (metal base variant) offer similar functionality for applications where plastic is unsuitable
For system integrators: The modular design allows field replacement of individual operator components without rewiring contact blocks or panel cutouts, reducing downtime during maintenance cycles.
