Schneider Electric ZB4BW7A3740 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BW7A3740 is an illuminated momentary push-button switch designed for industrial control panel applications. Fitted with an LED light source and a flush-style rectangular operator, this switch mounts through a 22 mm panel cutout and provides a clear on-off switching sequence. The chromium-plated metal bezel delivers durability in demanding environments, and the unit carries NEMA 4X and NEMA 13 ratings, making it suitable for wet, corrosive, and dusty locations. Licensed electricians and control panel builders install this switch in machine control, automation, and process equipment panels where a reliable, illuminated momentary input is required.

This switch is used in commercial and industrial control panel applications requiring a 22 mm mounting footprint. The dual-color availability in green and red makes it well suited for start and stop operator interfaces. Typical installations include motor control centers, machine tool panels, conveyor control stations, and general-purpose automation enclosures. The shock-resistant and vibration-resistant construction supports installations in high-cycle or high-vibration environments common in manufacturing and process industries.

Key Features

• 22 mm mounting hole diameter for standard industrial panel cutouts
• Momentary (on-off) switch sequence with LED illumination
• Flush rectangular operator available in green and red
• Chromium-plated metal bezel for corrosion and impact resistance
• NEMA 4X and NEMA 13 rated for wet and corrosive environments

Compatibility

Designed as an OEM-style replacement or new-installation component for industrial control panels requiring a 22 mm momentary illuminated push-button switch in NEMA 4X or NEMA 13 rated enclosures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines and applicable local codes. De-energize the control panel and verify zero voltage at the mounting location before beginning work. The switch mounts through a 22 mm panel cutout; ensure the panel thickness is compatible with the mounting hardware supplied. Do not exceed the rated voltage or current specifications of the switch operator or lamp circuit.
