Schneider Electric 9001K93R Mushroom Head Pushbutton Knob

Product Description

The SCHNEIDER ELECTRIC 9001K93R is a red, nonilluminated extended mushroom head pushbutton knob designed as a switch accessory for 30 mm pushbutton operator stations. This knob replaces or upgrades the actuator head on compatible pushbutton assemblies, providing a large-surface, palm-friendly target for emergency or frequent-contact switching applications. The extended mushroom head profile increases visibility and ease of actuation in industrial and commercial control panel environments. Installation is handled by qualified electricians or control panel technicians during panel assembly or field maintenance.

This knob is suited for use in industrial control panels, machine tool stations, and commercial equipment where 30 mm pushbutton operators are standard. The red color convention is commonly associated with stop, emergency, or caution functions in control circuit wiring. The nonilluminated design keeps the assembly simple and cost-effective where indicator lighting is not required. Typical applications include motor control centers, conveyor systems, process equipment, and general-purpose control enclosures.

Installation Notes

Installation should be performed by a qualified electrician or control panel technician. De-energize all control circuits and lock out the panel per NFPA 70E and applicable OSHA lockout/tagout procedures before servicing any pushbutton assembly. The knob typically threads or snaps onto the operator body — do not force-fit or over-torque the attachment to avoid cracking the actuator housing. Verify the replacement knob is fully seated and actuates freely before restoring power.
