Schneider Electric ZB4BW7A3741 Illuminated Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BW7A3741 is an illuminated momentary push-button switch designed for industrial control panel applications. Rated for a 22 mm mounting hole diameter, this switch features an LED light source and a flush-profile rectangular actuator with a chromium-plated metal bezel. It operates on a momentary (MO) on-off switch sequence, making it well-suited for start, stop, or command functions where sustained actuation is not required. The unit is rated NEMA 4X and NEMA 13, indicating resistance to corrosion, dust, and water ingress. Available in green and red actuator colors to support standard control panel color coding conventions.

This push-button switch is intended for use in industrial and commercial control panel assemblies where a 22 mm operator format is standard. Typical applications include machine tool panels, process control enclosures, and motor control centers. The shock-resistant and vibration-resistant construction supports use in environments with mechanical stress or continuous equipment vibration. Licensed electricians and panel builders install this type of operator as part of low-voltage control circuits governed by NEC and applicable IEC standards.

Key Features

• 22 mm mounting hole diameter — fits standard 22 mm panel cutouts
• Illuminated LED actuator in green or red for clear operator indication
• Momentary (MO) on-off operation — no latching action
• Flush rectangular push button with chromium-plated metal bezel
• NEMA 4X and NEMA 13 rated — corrosion, dust, and water resistant
• Shock-resistant and vibration-resistant construction

Compatibility

Designed as an OEM-style replacement or new-installation operator for industrial control panels requiring a 22 mm momentary illuminated push-button switch with LED indication.

Installation Notes

Installation should be performed by a qualified electrician or panel builder in accordance with NEC requirements and applicable IEC standards. De-energize the control panel and verify absence of voltage before installing or replacing panel operators. The 22 mm cutout should be clean and free of burrs to ensure proper bezel seating and NEMA-rated sealing. Do not exceed the rated electrical parameters for the switch contacts when wiring into the control circuit.
