Eaton M22S-WRK3 – Frequently Asked Questions

1) Will the Eaton M22S-WRK3 selector switch fit a standard 22.5 mm panel cutout?
Yes. The M22S-WRK3 knob selector operator mounts in a 22.5 mm panel hole, which is the standard cutout for the Eaton M22 line and for most metric pushbutton and selector devices. Overall body size is 1.17 in by 1.17 in with a height of 1.06 in, so allow that much clearance behind and around the hole once a contact block is stacked on.
2) Does the Eaton M22S-WRK3 come with contact blocks, or do I have to order them separately?
The operator head only. The M22S-WRK3 ships with a contact block mounting adapter, but the NO/NC contact blocks themselves are a separate order. Plan your contact count around the three switch positions before you buy.
3) Is this a maintained or spring-return selector switch?
Maintained in all three positions. Turn the knob and it stays there until someone moves it. If your sequence needs the knob to snap back to center after release (a jog or momentary start, for example), this is the wrong operator and you want a spring-return M22 selector instead.
4) Can this selector switch be used on a washdown line or an outdoor control panel?
Yes, within the enclosure rating. The M22 knob selector is rated IP66, NEMA 4X and NEMA 13, so it stands up to dust, hose-directed water and oily or corrosive atmospheres. The rating only holds if it's mounted in a correspondingly rated enclosure with the gasket seated properly in the 22.5 mm cutout.
5) Knob or lever selector for an M22 control station, which should I use?
This one is the knob version, model M22S-WRK3, with a black knob and black bezel. A knob gives a compact, firm grip and sits closer to the panel face, which suits crowded control stations and machines where an operator may brush past. A longer lever-style actuator is easier to throw with a gloved hand or from a distance. Switching function is identical; it's purely the feel and the panel profile that change.
6) Does this Eaton selector switch meet the approvals needed for a control panel going into Canada or Europe?
The M22 knob selector is CSA Certified and CE Marked, which covers the two approvals most often called out on industrial control panel submittals for Canadian and European destinations.
7) How many operations is this M22 selector switch rated for?
100,000 mechanical operations. For a hand-off-auto selector that gets moved a few times a shift that's a long service life, but on a station that's cycled hundreds of times a day it's worth stocking a spare head.
