Eaton M22 Key-Operated Two-Position Selector Switch, Momentary, IP66/NEMA 4X

The Eaton M22 Key-Operated Selector Switch is a modular, two-position control device built on Eaton's M22 pilot device platform for industrial and commercial control panels. This key-operated actuator provides momentary switching action that returns from the right position, with the key removable in the left position for controlled operator access. Rated IP66, NEMA 4X, and NEMA 13, the switch is built for washdown, wet-location, and corrosive-environment applications, and is engineered for 100,000 operating cycles. The switch is non-illuminated and is offered across a range of bezel colors, button colors, and key-removal configurations within the M22WS series.

Eaton M22-WS – Frequently Asked Questions

1) Does the key come out in both positions on this Eaton M22 key switch?
No. As supplied, the key is removable in the left position only, and the switch is momentary with return from the right. So the operator turns right to act, it springs back, and the key can only be pulled with the switch at rest. The description notes the removal positions can be changed in the field using coding adapters if you need a different arrangement.
2) Can this key switch be used in a washdown or outdoor control station?
Yes. The switch carries IP66, NEMA 4X and NEMA 13 protection, which covers dust, hose-directed washdown water, corrosive atmospheres and oil or coolant spray. That makes it usable in food processing, car wash, chemical and other wet-duty panels as long as the enclosure itself carries a matching rating.
3) Does the Eaton M22-WS key switch come with contact blocks?
No contact blocks are included. What ships with it is one key and one contact block mounting adapter, so you still need to order M22 contact blocks separately and pick the NO/NC arrangement your control circuit calls for. Budget for that when you quote the panel.
4) What is the difference between key code MS1 and MS2 on the Eaton M22 key switch?
The two orderable versions differ only in key coding: M22-WS is the MS1 key code and M22-WS-MS2 is the MS2 key code. Use one code throughout a facility if you want a single key to serve every station, or split codes when you want separate operators restricted to separate machines.
5) Should I use a key-operated selector switch or a standard selector switch on a machine panel?
Pick the key version when only authorized staff should be able to make the selection, such as bypass, maintenance mode, or restricted start functions. This one is two-position and momentary, returning from the right, so it cannot be left latched in the active state, which suits jog, reset, or override duty rather than a maintained run/stop selection. If any operator on the floor needs to make the change and the setting should hold, a standard maintained knob selector is the right part instead.
6) Does the Eaton M22-WS key switch carry CE and CCC marking for export machinery?
Both. The switch is CE marked and CCC marked, which covers machines being shipped into the European and Chinese markets. Environmental protection is declared as IP66/NEMA 4X/NEMA 13.
7) How long will an Eaton M22 key selector switch last in daily use?
The actuator is rated at 100,000 operating cycles mechanically. At a dozen operations a shift that is years of service; on a high-frequency reset function that gets hit hundreds of times a day, plan on it as a wear item and stock a spare.
8) Is this M22 key switch illuminated, and what does the front look like?
It is non-illuminated, with a silver bezel and black actuator, so it matches the standard chrome-bezel M22 devices already on most industrial panels. If you need a lit indication of the selected state, that has to come from a separate M22 indicator light.
