Schneider Electric ZB4BW35 Illuminated Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BW35 is an illuminated, momentary push-button switch designed for industrial control panel applications. Built with a metal body and a flush-profile, round orange actuator, this switch fits a standard 22 mm mounting hole. It carries a NEMA 4X and NEMA 13 rating, making it suitable for use in wet, dusty, and corrosive environments. Licensed electricians and industrial control panel builders install this switch as part of operator interface assemblies, machine control stations, and process automation panels. The momentary action means the circuit activates only while the button is depressed and returns to its normal state upon release.

This switch is a direct-fit component for 22 mm diameter panel cutouts found in standard industrial enclosures. The illuminated orange actuator provides clear visual feedback to operators on active machine floors, making it well suited for use in manufacturing, process control, and utility applications. Its certifications cover a broad range of international and North American standards, which supports use in both domestic and export equipment builds. Panel builders working to UL 508A or similar standards will find this switch compliant across multiple certification bodies.

Key Features

• 22 mm mounting hole diameter for compatibility with standard industrial panel cutouts
• Illuminated orange round actuator for clear operator visibility
• Flush push-button profile for low-profile panel designs
• Metal actuator construction for durability in demanding environments
• NEMA 13 and NEMA 4X rated for protection against dust, oil, and corrosive agents
• Momentary operation returns to normal state when released

Compatibility

Designed as a direct replacement or new-installation push-button switch for 22 mm industrial control panel cutouts meeting applicable IEC and UL standards.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize the control panel and lock out all power sources before mounting or wiring the switch. A standard 22 mm panel punch or hole saw is required for new cutouts. Follow the manufacturer wiring diagram for the illumination circuit to ensure the lamp or LED element is connected correctly.
