22 mm Green Push Button Operator

The Schneider Electric ZB5AH03 is a 22 mm flush push button designed for industrial control panels. It uses a maintained action so the contacts stay in the selected position until pressed again. The green colour provides clear visual identification on machinery and process equipment. Panel builders and maintenance engineers specify it for standard operator stations.

Replaces worn or missing 22 mm operators

This unit fits the industry-standard 22 mm mounting cut-out, allowing direct replacement of damaged buttons without re-drilling the enclosure. The jump is worth it when the existing head is cracked, the legend is illegible or the sealing has degraded. It is not for applications requiring momentary action, illuminated heads or a different colour code.

IP66 and NEMA 4X sealing for harsh environments

The plastic bezel and head meet IP66 and NEMA 1, 2, 3, 4, 4X, 13 ratings, resisting high-pressure wash-down and corrosive atmospheres. It comfortably handles food-processing splash zones, outdoor panels and chemical plant areas. It runs out where metal bezels are mandated by specification or where a keyed or mushroom-head operator is required for safety functions.

Questions about this item

What panel cut-out size does the 22 mm green push button operator require?

The operator fits a standard 22 mm panel cut-out, which is the mounting dimension specified for this flush button.

How is the maintained flush button secured during installation, and what step is often missed?

The plastic bezel threads into the panel cut-out and is locked with the supplied fixing nut; the step often missed is tightening the nut to the specified torque so the IP66 seal seats correctly.

Which component will need replacement if the green lens fades or cracks after prolonged UV exposure?

The flush button head is a single moulded plastic piece; if the green lens deteriorates, the entire operator head must be replaced.
