Schneider Electric ZB4BW34 Illuminated Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BW34 is an illuminated, momentary push-button switch designed for industrial control panel applications. It features a flush-style, round red metal button mounted through a 22 mm panel hole. The momentary (MO) operation type means the circuit is active only while the button is pressed, making it well-suited for start, stop, or jog functions. The metal construction and NEMA 4X and 13 ratings indicate suitability for environments exposed to washdowns, dust, and corrosive conditions. Licensed electricians and control panel builders are the primary installers of this component.

This push-button switch is used in industrial and commercial control panels where a clearly visible, illuminated actuator is required. The red color convention typically signals stop or emergency-related functions, though final wiring and labeling are determined by the panel designer. The 22 mm mounting hole diameter is a widely adopted standard in industrial operator interface hardware, allowing integration into a broad range of enclosures and panel cutouts. The compact 1.3 x 1.3 x 1.3 inch body fits standard panel layouts without requiring extra clearance.

Key Features

• Illuminated flush-style actuator provides visible status indication at the panel face
• Momentary (MO) operation — circuit closes only while button is depressed
• Round red metal button construction for durability in industrial environments
• 22 mm mounting hole diameter fits standard industrial panel cutouts
• NEMA 4X and 13 rated for protection against dust, oil, and washdown conditions
• Certified to UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and multiple additional international standards

Compatibility

Designed as an OEM-style replacement or new-installation component for industrial control panels using the standard 22 mm operator interface format.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local electrical codes. Disconnect and lock out all power to the control panel before removing or installing any switch components. Verify the illumination voltage and contact configuration match the circuit design before wiring. Do not exceed the rated voltage or current for the switch contacts.
