22 mm Industrial Push Button
The Schneider Electric ZB4BA9 is a 22 mm flush momentary push button designed for industrial control panels and automation equipment. It suits engineers and maintenance teams who need a reliable operator for machine start, stop or reset functions in demanding environments.
Metal Construction and Sealing
The operator uses metal for the head, bezel and basic material, meeting NEMA 1, 2, 3, 4, 4X, 13 and IP66, IP69K ratings for dust and high-pressure wash-down resistance. It complies with standards including IEC 60947-5-1, UL 508 and DNV, and operates in Class I IEC 60536 installations.
Panel Mounting and Compliance
The 22 mm cut-out fits standard industrial panels, while the flush profile reduces accidental actuation and snagging. Certifications cover CSA C22.2 No. 14, Bureau Veritas, GL, LROS and JIS C8201-5-1, with REACH and RoHS compliance confirmed. Not suited for applications requiring maintained action or illuminated feedback.

Questions about this item
How do I install the 22 mm flush momentary push button in a panel?
Drill a 22 mm hole, insert the operator from the front, secure the metal bezel with the locking nut from behind, then snap the contact block onto the rear until it clicks.
What maintenance or replacement will the push button need over time?
The metal head and bezel resist wear; inspect the IP66 and IP69K seals periodically and replace the contact block if switching feels inconsistent.
What limit appears first during continuous operation of the push button?
The momentary action returns automatically on release, so the mechanical endurance of the internal spring and contact block determines sustained-use life.
