A 22 mm blue maintained push button with metal construction, IP66 and NEMA 4X protection for industrial control panels
The Schneider Electric extended push button is a 22 mm industrial control component designed for panel mounting in automation and machinery applications. Its blue colour coding supports quick visual identification on busy control panels. The maintained action suits functions that require a latched on or off state without continuous pressure. Metal construction throughout the operator, head and bezel provides mechanical durability in demanding environments.
Rated NEMA 13 and 4X with IP66 ingress protection, the button resists dust, water jets and oil during continuous operation. Compliance with IEC 60068-2-6 and IEC 60068-2-27 confirms vibration and shock tolerance for long-term mounting on moving equipment. The metal bezel and head maintain sealing integrity over repeated cycles without the degradation seen in plastic alternatives. Standards including EN/IEC 60947-5-1 and UL 508 verify reliable electrical performance under extended duty.
This unit replaces worn or damaged 22 mm push buttons where a maintained blue operator is specified in the wiring schematic. The jump is worthwhile when the existing device lacks NEMA 4X or IP66 sealing, or when metal construction is required for impact resistance. It is not suited for momentary-only circuits, illuminated applications or panels cut to a different mounting diameter. Builders needing a different colour code or legend plate must select an alternative operator.

As a passive mechanical switch it draws no operating current and produces no heat; only the control circuit it actuates carries load.
It fits a standard 22 mm panel hole and is secured with the supplied metal locking nut; no additional adapters are needed.
Yes, the operator meets EN/IEC 60947-5-1 and mounts directly to any legacy contact block certified to the same standard.
