Schneider Electric ZB5AW143 Illuminated Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AW143 is an illuminated, momentary push-button switch designed for industrial control panel applications. It features a 22 mm mounting hole diameter, a red round extended (straight) operator, and a plastic push-button body. The momentary (MO) operation type means the switch returns to its default state upon release. Rated NEMA 4X and NEMA 13, this switch is built to resist dust, oil, and water ingress, making it suitable for demanding environments. It carries a broad range of international certifications, including UL 508, CSA, and EN/IEC 60947-5-1, confirming compliance for use in industrial machinery and control circuits.

This push-button switch is suited for use in industrial control panels, machine tool enclosures, and operator interface stations where a clearly visible, illuminated momentary actuator is required. The red color coding makes it appropriate for stop, emergency, or alert functions in control panel layouts. It is typically installed by licensed electricians and panel builders working on industrial automation, manufacturing equipment, and process control systems. The 22 mm mounting diameter fits the widely used 22 mm industry-standard panel cutout.

Compatibility

Designed as an OEM-style replacement or new-installation push-button switch for industrial control panels using the standard 22 mm mounting hole format.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize the control panel and verify zero voltage at the mounting location before beginning installation or wiring. Ensure the panel cutout is clean and properly sized to the 22 mm specification before mounting the switch body. Do not exceed the electrical ratings specified on the product datasheet for the intended control circuit.
