Schneider Electric ZB4BW31 Illuminated Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BW31 is an illuminated, momentary push-button switch designed for industrial control panel applications. Featuring a 22 mm mounting hole diameter, this switch uses a flush-mount, round white metal operator and is rated for momentary (MO) operation. At 0.05 pounds, it is a compact component measuring approximately 1.1 inches in length and 1.3 inches in both height and width. It carries UL Listed status and meets multiple international standards, making it suitable for demanding industrial environments. Licensed electricians and control panel builders install this switch as part of operator interface assemblies on machine control enclosures.

The ZB4BW31 is used in industrial and commercial control panel builds where illuminated operator feedback is required. Its 22 mm format fits standard 22 mm cutouts common across pushbutton stations, enclosures, and operator interface panels. The NEMA 4X and NEMA 13 ratings make it appropriate for washdown, dust-tight, and corrosion-resistant enclosure applications in manufacturing, process control, and marine environments. This switch is installed by licensed electricians and panel builders working to NEC and applicable machine safety codes.
