A 22 mm white flush push button with momentary action, IP66 and NEMA 1, 13, 2, 3, 4, 4X ratings for industrial control panels
This Schneider Electric push button is a 22 mm momentary operator designed for industrial control panels and automation systems. It suits engineers and maintenance teams who need a reliable manual input for machinery start, stop or reset functions. The white plastic head provides clear visibility in panel layouts. Its booted design helps protect the actuator in demanding environments.
The device carries NEMA ratings 1, 2, 3, 4 and 4X alongside an IP66 ingress protection rating. This combination means the button withstands falling dirt, dripping water, rain, sleet, windblown dust and hose-directed water. It is not rated for prolonged immersion or environments requiring NEMA 6 or 6P protection. Installers must verify that the enclosure rating matches the application requirements.
This unit replaces damaged, faded or obsolete 22 mm push buttons that no longer meet current safety or environmental standards. The upgrade is worthwhile when panels require compliance with IEC 60947-5-1, UL 508 or the listed DNV, Bureau Veritas and CSA certifications. It is not suited for applications needing illuminated heads, mushroom operators or maintained contact action.

The white colour is a standard choice for general start or reset functions; select a different colour only if your control scheme assigns a specific meaning to another shade.
IP66 guarantees the installed button is dust-tight and protected against powerful water jets, so it survives wash-down and outdoor exposure without ingress.
EN/IEC 60947-5-1 and UL 508 define the 22 mm cut-out dimensions and electrical ratings, capping the button at 6 A / 600 V AC for industrial control circuits.
