Schneider Electric 9001K17B Mushroom Head Pushbutton Knob

Product Description

The SCHNEIDER ELECTRIC 9001K17B is a 2.25-inch snap-in extended mushroom head pushbutton knob designed as a replacement accessory for 30 mm pushbutton operator assemblies. Made from polycarbonate, this round, black, nonilluminated knob snaps directly into compatible operator bodies without tools in most cases. It measures 2.8 inches in length, 2 inches in width, and 2.3 inches in height, and weighs 0.11 pounds. Electricians and control panel technicians use this knob to restore or reconfigure operator heads on existing pushbutton stations without replacing the full assembly.

This snap-in knob is intended for use in industrial and commercial control panel applications where 30 mm pushbutton operators are standard. It is suited for machine control stations, motor starter panels, and operator interface enclosures. The extended mushroom head profile provides a larger contact surface, making it practical for emergency-stop-style or high-visibility operator applications. Installation is typically performed by electricians or automation technicians during panel assembly or field service.
