Schneider Electric ZB4BW36 Push-button Switch 22mm Blue

Product Description

The SCHNEIDER ELECTRIC ZB4BW36 is a momentary, nonilluminated push-button switch designed for industrial control panel applications. It features a flush-style, round blue metal operator with a 22 mm mounting hole diameter. The momentary (MO) action means the switch activates only while depressed and returns to its default state upon release. Rated NEMA 4X and NEMA 13, it is built for environments where dust, oil, and water resistance are required. Electricians and control panel builders working on machinery, automation systems, and process equipment are the primary installers of this device.

The ZB4BW36 is suited for industrial control panels in manufacturing, process automation, and machine control applications. Its NEMA 4X rating makes it appropriate for washdown or wet environments in addition to standard indoor use. The flush button profile reduces the risk of accidental actuation, making it a practical choice for panels where inadvertent triggering is a concern. It is typically wired as a discrete input to a relay, PLC, or motor starter circuit in both light commercial and heavy industrial settings.
