Schneider Electric 9001R20 Mushroom Head Pushbutton Operator

Product Description

The SCHNEIDER ELECTRIC 9001R20 is an extended mushroom head pushbutton operator designed for use with 30 mm industrial control stations. This red, round, illuminated knob serves as the operator component — the visible and tactile actuator that a technician or operator presses to trigger the switching action in the control circuit. Made from polycarbonate, it provides durability in demanding panel and control station environments. The extended mushroom head profile is a common choice for emergency-stop or high-visibility applications where quick, unmistakable actuation is required. Electricians and control panel technicians install this operator as a replacement or new-build component in machine control, automation, and process equipment panels.

This operator is rated for use with Harmony 9001K, 9001SK, and 9001KX series 30 mm pushbutton assemblies, as well as K2L illuminated pushbutton units. It is suited for industrial control panel applications in both light manufacturing and heavy process environments. The illuminated configuration supports visual feedback at the operator interface, making it appropriate for panels where status indication at the pushbutton is required. Install scenarios typically include machine tool control stations, motor control centers, and process control enclosures.

Installation Notes

Installation is performed by a licensed electrician or qualified control panel technician. De-energize and lock out the control panel per NFPA 70E and applicable OSHA lockout/tagout procedures before removing or installing any pushbutton operator. The operator mounts to a compatible 30 mm contact block or illuminated pushbutton body — confirm the base unit series matches the 9001K or K2L families before installation. Do not force the operator onto an incompatible base, as polycarbonate components can crack under excessive torque or misalignment.
