A 22 mm flush momentary push-button operator with a snap-fit modular design for industrial control panels
The Schneider Electric ZB4BA3 is a flush-mounted push-button operator with momentary action designed for 22 mm panel cutouts. It belongs to the Harmony range of modular industrial controls built for robust construction and simple setup.
Confirm the mounting surface provides a standard 22 mm opening and that the momentary contact type matches your control circuit requirements. The operator uses a snap-fit head with a single-screw metal collar for secure attachment without periodic retightening.
This unit suits engineers fitting or maintaining industrial panels that require a durable momentary flush button. It is not intended for maintained or latching action, nor for applications needing an integrated pilot light or selector switch function.

The operator uses a snap-fit head and body that tightens with a single screw onto a fully metal 22 mm mounting collar; collar and contact blocks are separate modules you select for the application.
Select the ZB4 metal range when you need chromium-plated metal bezels and a fully metal collar for harsher environments; choose ZB5 plastic for round or square plastic bezels in less demanding settings.
The 22 mm figure is the standard panel hole diameter; the operator head and body snap together and lock onto the metal collar through that hole, providing a secure, shake-proof mount without periodic retightening.
