Schneider Electric ZB5AA5 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB5AA5 is a non-illuminated, momentary push-button operator designed for use in industrial control panels and machine operator interfaces. The flush-mount, round yellow button fits a standard 22 mm mounting hole and is constructed from plastic. It is a momentary (MO) type, meaning the circuit activates only while the button is depressed and returns to its default state upon release. The ZB5AA5 carries a NEMA 4X and NEMA 13 rating, making it suitable for environments requiring protection against dust, oil, and water ingress. Electricians and control panel builders are the primary installers for this component.

This push-button operator is used in residential, commercial, and industrial control panel builds, motor control centers, and machine tool enclosures where a momentary switching action is required. The yellow color designation is commonly applied to specific functional indicators in panel layouts, such as caution or return-to-normal functions. Its non-illuminated design keeps the assembly simple in applications where indicator lighting is not required or where lighting is provided separately.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes. De-energize the control panel and verify absence of voltage before mounting or wiring the operator. The operator head mounts through a 22 mm panel cutout and typically secures with a threaded collar or contact block assembly — ensure the contact block is fully seated and locked before restoring power. Do not exceed the ratings of the associated contact block or switching element paired with this operator.
