A 22 mm momentary flush pushbutton rated IP69K and NEMA 4X for industrial control panels
This Schneider Electric pushbutton is a 22 mm momentary flush operator built for industrial electrical control panels. Its all-metal head, bezel and basic material suit machine builders and maintenance teams who need a durable manual input device. The white colour provides clear visibility on dark enclosures. It meets a long list of international standards including IEC 60947-5-1 and UL 508.
The operator carries NEMA 13 and 4X ratings plus IP69K ingress protection, so it resists water jets, oil and dust in harsh environments. Metal construction withstands mechanical shock per IEC 60068-2-27 and vibration per IEC 60068-2-6. Compliance with CSA C22.2 No. 14, DNV, GL and LROS confirms suitability for marine and heavy-industry installations.
Momentary flush operation returns automatically when released, making it suitable for jog, start or reset functions that see repeated actuation. The boot design and metal materials maintain sealing and mechanical integrity over long production runs. Bureau Veritas certification and REACH and RoHS compliance support use in regulated facilities worldwide.

Mount the metal operator through a 22 mm cutout, secure the locking nut to the rated torque, then snap the contact block onto the operator until it clicks; the click is the step installers sometimes skip.
The momentary contact block is the wear item; replace it when switching becomes unreliable, while the IP69K-rated metal head and bezel remain sealed.
The contact block reaches its rated electrical endurance before the IP69K-sealed metal operator shows mechanical degradation.
