Schneider Electric 9001B11 Selector Switch Knob 30 mm Black

Industrial Selector Switch Knob

The Schneider Electric 9001B11 is a standard switch knob designed for non-illuminated selector switches in industrial control panels. It provides a tactile interface for operators managing machinery or electrical circuits in automation environments. The component suits maintenance engineers and panel builders who need a direct replacement part for existing Schneider Electric assemblies. Its 30 mm diameter matches the mounting specification for the designated switch series.

Build Quality and Daily Use

The black finish resists fading and surface wear in workshops or outdoor enclosures exposed to dust and oil. A secure press-fit onto the switch shaft prevents the knob from loosening during vibration or frequent actuation cycles. The 30 mm size gives a firm grip for gloved hands without protruding excessively from the panel face. No illumination window means the surface stays uniform, simplifying cleaning and visual inspection during routine checks.

Practical Limits of the Interface

This knob fits only non-illuminated selector switches with a compatible 30 mm shaft profile, so it cannot be used on illuminated, push-pull or key-operated variants. The part carries no electrical rating of its own; all voltage and current limits belong to the switch body it mounts on. Buyers who need a different diameter, colour coding or an illuminated cap must select a different reference from the Schneider Electric range.
