22 mm metal extended pushbutton with maintained action, IP66 and NEMA 4X sealing for industrial panels
The Schneider Electric 22 mm Extended Pushbutton is a maintained industrial control device built for panel mounting. Its metal construction and black finish suit harsh environments where reliable manual actuation is required. Operators in automation, marine and heavy-equipment sectors use it for start-stop or mode-selection tasks. The maintained action keeps the circuit in its last position until pressed again.
The pushbutton carries NEMA 1 2 3 4 4X 13 and IP66 ratings, giving it protection against dust, water jets and corrosion in indoor and outdoor installations. It handles vibration and shock per IEC 60068-2-6 and IEC 60068-2-27, and meets Bureau Veritas, DNV, GL and LROS marine approvals. The device is not rated for submersion beyond the IP66 test conditions or for hazardous-location use without additional enclosures.
The operator conforms to EN/IEC 60947-1 60947-5-1 60947-5-4 60947-5-5 and UL 508, defining its electrical endurance and making it suitable for control-circuit duty. It also satisfies CSA C22.2 No 14, JIS C8201-1 8201-5-1 and IEC 60529 for ingress protection. The maintained mechanism is not designed for momentary or safety-rated emergency-stop functions that require different standards compliance.

Yes, it uses the standard 22 mm mounting diameter so it matches other 22 mm Schneider operators you already have installed.
Press the extended black head — it should latch in the maintained position; release requires a second press. The metal bezel and IP66 seal should show no ingress when tested.
Only the extended pushbutton head is supplied; contact blocks and legend plates are sold separately.
