Industrial push button for control panels

The Schneider Electric ZB4BW33 is a 22 mm flush illuminated push button in green designed for industrial electrical controls and automation. Its metal head, bezel and basic material suit panels that require a momentary operator with a clear visual indicator.

Suited for sealed enclosures.

This operator carries NEMA 13 and 4X ratings plus IP66 and IP69K ingress protection, so it fits panels that must resist water jets, high-pressure wash-down and oil. Builders who need a non-illuminated actuator or a different mounting diameter should look at other series.

Maintains sealing under continuous vibration

The device meets IEC 60068-2-6 and IEC 60068-2-27 for vibration and shock, and IEC 60529 for sustained ingress protection, so the seal holds during prolonged machine operation rather than only during brief actuation. Compliance with EN/IEC 60947-5-1, -5-4 and -5-5 confirms reliable performance in safety-related circuits.
