22 mm White Illuminated Push Button

The Schneider Electric ZB5AW31 is a 22 mm flush-mounted illuminated push button designed for industrial control panels and automation systems. Its white plastic head and bezel provide clear visual indication in machine interfaces. The operator suits maintenance engineers and panel builders who need a momentary action device rated for harsh environments.

Panel Mount Installation and Common Issues

The 22 mm cut-out matches standard industrial panel openings, allowing the operator to snap into place without specialised tools. A frequent problem occurs when the mounting nut is over-tightened, cracking the plastic bezel or distorting the seal. Misalignment during insertion can also prevent the locking clips from engaging fully, leading to loose operation or water ingress.

Environmental Limits of the IP66 and NEMA Ratings

The IP66 rating guarantees protection against powerful water jets and total dust ingress, while NEMA 13 and 4X ratings confirm resistance to oil, coolant and corrosion. These standards do not protect against continuous submersion or high-pressure steam cleaning. The plastic construction also limits use in areas with heavy mechanical impact or extreme UV exposure.

Questions about this item

How do I confirm the ZB5AW31 is functioning correctly after wiring?

Press the white flush operator and verify the momentary action closes and opens the contact block cleanly, with the IP66 seal intact and no water ingress under NEMA 4X or 13 conditions.

What components are included with the ZB5AW31 and what must be purchased separately?

The package contains the white 22 mm plastic flush push-button operator head only; a matching contact block, light module and legend plate are not included and must be ordered separately.

Which version of the 22 mm illuminated push button should I select for my panel?

Choose the ZB5AW31 when you need a white, momentary, flush plastic operator rated IP66 and NEMA 13/4X; other colours or maintained-action types carry different part numbers.
