Schneider Electric ZB5AW343 Illuminated Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AW343 is an illuminated, momentary push-button switch designed for industrial control panel applications. It features a 22 mm mounting hole diameter and a flush-style, round red plastic operator. The momentary (MO) action returns the switch to its default state upon release, making it suitable for start, stop, or signal functions in control circuits. Weighing 0.03 pounds and measuring 1.3 x 1.3 x 1.3 inches, the ZB5AW343 is a compact unit rated for NEMA 4X and 13 enclosure environments. It carries a broad range of international certifications, including UL 508 listing, CSA C22.2 No. 14, and EN/IEC 60947-5-1, confirming its suitability for demanding electrical installations.

The ZB5AW343 is suited for use in industrial and commercial control panels, machine operator interfaces, and automation equipment. Its NEMA 4X rating makes it appropriate for installations requiring resistance to dust, oil, and washdown conditions. Electricians and controls technicians install this switch in both new panel builds and replacement scenarios where an illuminated momentary operator is required. The 22 mm mounting hole is a widely used standard size across industrial enclosures and operator interface hardware.

Compatibility

Designed as an OEM-style replacement or new-installation illuminated momentary push-button operator for industrial control panels and machine interfaces using 22 mm mounting hole diameter cutouts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the control panel before mounting or wiring the switch. The 22 mm panel cutout must be clean and free of burrs to ensure proper seating and NEMA-rated sealing. Verify that the control circuit voltage matches the lamp and contact ratings of the switch assembly before energizing.
