Schneider Electric ZB4BL5 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BL5 is a 22 mm momentary push-button switch operator designed for industrial control panel applications. The extended, straight-profile yellow round button is nonilluminated and constructed with a metal push-button body. It mounts through a standard 22 mm panel cutout and provides momentary contact actuation, returning to its neutral position immediately upon release. This component is typically installed by licensed electricians or control panel integrators working on motor control centers, machine control panels, and similar industrial equipment. Its NEMA 4X and 13 ratings confirm suitability for wet, corrosive, and washdown environments.

This operator is suited for use in commercial and industrial control panel assemblies where a 22 mm momentary switch is required. Common applications include machine start or stop functions, conveyor controls, and process equipment panels. The yellow color provides a recognized visual indicator for specific operator functions, such as caution or return-to-normal actions, in accordance with standard panel color-coding practices. Panel builders and electricians integrating this into enclosures will find the extended button profile appropriate for standard industrial operator interface layouts.
