22 mm Flush Push Button

The Schneider Electric ZB5AA2 is a 22 mm flush push button designed for industrial control panels. It provides a momentary contact action suited to machine start, stop or reset functions. The black plastic head and bezel integrate with standard 22 mm panel cut-outs.

Replaces worn or outdated 22 mm operators

This unit fits existing 22 mm cut-outs, allowing direct replacement of damaged or obsolete flush buttons without panel modification. The upgrade is worthwhile when the original operator no longer meets NEMA 1, 2, 3, 4, 4X or 13 sealing requirements or when certifications such as IP66 and IP69K become mandatory.

Sealed for continuous harsh environments

The plastic construction meets IP66 and IP69K ratings, resisting high-pressure wash-down and dust ingress during sustained operation. Compliance with IEC 60947-5-1, IEC 60529 and UL 508 ensures reliable performance under vibration, shock and temperature cycling defined by IEC 60068-2-6 and IEC 60068-2-27.

Questions about this item

Will this 22 mm flush push button fit a standard 22 mm panel cut-out?

Yes, the operator is sized for a 22 mm mounting hole and the flush head sits level with the panel surface once secured.

How do I install the ZB5AA2 and what step is often missed?

Insert the operator through the 22 mm cut-out, tighten the locking nut from behind, then snap the contact block onto the rear until it clicks — forgetting the click leaves the circuit open.

What maintenance or replacement will this push button need over time?

The plastic head and bezel resist IP66 and IP69K wash-downs, but inspect the seals after heavy vibration (IEC 60068-2-6) and replace the operator if the momentary action feels stiff or fails to return.
