Eaton M22 Modular Illuminated Selector Switch, Knob Operator, Two-Position
The Eaton M22 Modular Illuminated Selector Switch is a 22.5 mm panel-mount pilot device built around a momentary knob actuator with an illuminated bezel. Configured as a two-position selector, it delivers reliable state selection for industrial control panels and machine interfaces, and it is rated IP66, NEMA 4X, and NEMA 13 for use in harsh, wash-down, and outdoor-adjacent environments. Backed by Eaton's M22 modular platform, this operator is engineered for long service life and field flexibility.
Key Features
- Compact Modular Size: 22.5 mm mounting diameter fits standard M22 series panel cutouts for space-efficient control layouts.
- Two-Position Configuration: Selector switch operates between two distinct positions for clear, deliberate mode or state selection.
- Momentary Knob Actuator: Knob-style actuator with momentary action returns to its resting position after release, ideal for spring-return control functions.
- Illuminated Bezel: Illuminated design provides clear visual status indication on the panel face.
- Long Operational Life: Light rated for 100,000 hours and button rated for 100,000 operations, supporting demanding duty cycles.
- Field-Convertible Operation: Includes a contact block mounting adapter and can be converted in the field to maintained operation by removing the color-coded adapter.
- Rugged Environmental Rating: IP66, NEMA 4X, and NEMA 13 rated for protection against dust, water, and corrosive wash-down conditions.

Eaton M22-WLKV-W – Frequently Asked Questions
1) Will the Eaton M22 illuminated selector switch fit my existing 22 mm panel cutout?
Yes. The M22 knob operator mounts in the standard 22.5 mm panel hole used across the M22 series, so it drops into an existing 22 mm cutout without redrilling the panel face.
2) Is the Eaton M22-WLK knob selector momentary or maintained?
It ships as momentary, so the knob spring-returns to rest when released. The operator includes a contact block mounting adapter, and pulling off that color-coded adapter converts it to maintained action in the field, so one part covers both spring-return and latched two-position control.
3) Do I get the contact blocks with the M22 illuminated knob selector, or do I order those separately?
What you get is the operator itself, a two-position illuminated knob with a silver bezel, plus the contact block mounting adapter. The switching contact blocks and the LED element are separate M22 modular parts, so plan the order around the number of N.O./N.C. contacts your circuit needs and the lamp voltage for your panel.
4) Can this Eaton selector switch go on a wash-down machine in a food plant or an outdoor control station?
It is rated IP66, NEMA 4X and NEMA 13, which covers dust, hose-directed water and oil or coolant mist, so wash-down duty and corrosive areas are in scope. NEMA 4X also handles outdoor-adjacent enclosures. The rating applies to the front of the panel once the operator is correctly tightened into the cutout.
5) What colors does the Eaton M22 illuminated two-position knob selector come in?
Two: yellow/white (M22-WLK-Y) and red/white (M22-WLKV-W). Both carry the silver bezel. Red/white is the usual pick where the station signals a stop or alarm condition; yellow/white is common for mode or auxiliary selection.
6) Should I use an illuminated knob selector or a plain non-illuminated one for my control panel?
Go illuminated when the operator needs to see the selected state from across the floor or the panel face is crowded, since the lit bezel confirms the position at a glance. A non-illuminated knob is the simpler build: no lamp element, no control voltage run to the device, fewer parts to stock. The M22-WLK is the illuminated version, so it needs an LED element and a supply to feed it.
7) Can I use this as a two-position hand/off or run/stop selector on an HMI station?
That is what the two-position configuration is for: one distinct position each way for mode or state selection on machine control stations and panel-mount operator installations. Note the default momentary action, which means it will not stay in the selected position unless you remove the adapter to make it maintained, so a hand/off style selector that must hold its position needs that conversion.
8) How long will this selector switch and its light last in a high-cycle machine application?
The button is rated for 100,000 operations and the illumination for 100,000 hours. On a machine where an operator throws the selector a few hundred times a shift, that is years of service; for very high cycle counts on a per-part basis, budget the operator as a wear item.
