Eaton M22-WK Knob Type Operator 22.5mm

Product Description

The EATON M22-WK is a knob type operator designed for use with 22.5mm modular control stations and pushbutton enclosures. It provides a rotary manual actuation interface for control circuits in industrial and commercial electrical panels. The M22-WK mounts directly to compatible 22.5mm base contact blocks and enclosure fronts, giving operators a positive, tactile means of actuating switching elements. At 0.05 pounds and compact in size, it is a straightforward replacement or new-installation component handled by licensed electricians and panel builders.

The M22-WK is suited for industrial control panels, machine tool enclosures, motor control centers, and similar applications where a knob-style operator is preferred over a pushbutton or selector switch. It fits the 22.5mm mounting cutout standard common across modular control station product lines. Typical installations include start-stop stations, local disconnect controls, and operator interface panels in manufacturing, processing, and building automation environments.

Installation Notes

Installation is performed by a licensed electrician. De-energize and lock out the control panel per NFPA 70E procedures before removing or installing any operator component. Verify the mounting cutout is 22.5mm and that the contact block behind the operator is rated for the circuit being controlled.
