22 mm maintained push button operator

The Eaton M22M-DRH-S is a 22 mm extended push button operator designed for industrial control panels. Its metal construction and chrome die-cast aluminium bezel suit harsh environments. The operator is rated NEMA 1, 2, 3, 4, 4X, 13 and IP67, IP69K for ingress protection. It ships with a metal bezel and a contact block mounting adapter.

Field-convertible momentary-to-maintained action

This operator replaces fixed-function momentary or maintained buttons by offering field conversion between the two modes. The jump is worth it when a single stock-keeping unit must cover both operating styles in the same panel layout. Bureau Veritas, CCC, CE, CSA, GOST-R, Lloyd's Register and UL listings support compliance across multiple jurisdictions. The black finish provides consistent panel aesthetics.

Panel cut-out and contact block compatibility

Verify that the panel cut-out matches the 22 mm mounting diameter before ordering. Confirm that the chosen contact blocks fit the supplied mounting adapter and meet the application's electrical ratings. The maintained action suits latching functions; buyers who need momentary-only operation should consider the conversion step. No legend plate is included.

Questions about this item

Will the 22 mm cut-out accept this operator in a standard panel?

Yes, the operator is designed for a 22 mm mounting hole and includes a metal bezel and contact-block mounting adapter for secure panel fit.

How do I switch the operator from momentary to maintained action?

The unit is field-convertible; remove the operator head, rotate the internal cam to the maintained position, then reassemble — skipping the cam rotation is the common error.

What ongoing checks do the IP67 and IP69K seals require?

Inspect the bezel gasket and mounting nut torque periodically; replace the gasket if it shows cracking or compression set to maintain the rated ingress protection.
