Schneider Electric ZB4BA18 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BA18 is a momentary push-button switch operator designed for industrial control panel applications. It features a flush-style, round white button in a metal construction and mounts into a standard 22 mm panel cutout. The switch is non-illuminated and operates on a momentary contact basis, returning to its default state immediately upon release. Licensed electricians and control panel builders install this component in machine control stations, operator interface panels, and industrial enclosures where a clean, durable actuator is required. It carries a broad set of international certifications, making it suitable for domestic and export equipment builds.

The ZB4BA18 is used in residential, commercial, and industrial control panel assemblies wherever a 22 mm momentary actuator is needed. It is rated NEMA 4X and NEMA 13, meaning it is suitable for washdown environments and areas with oil or coolant exposure. Typical applications include motor start and stop stations, conveyor controls, machine tool panels, and process equipment operator interfaces. The metal push-button material provides durability in demanding shop floor and industrial environments.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation actuator for 22 mm industrial push-button switch assemblies using standard modular operator and contact block configurations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button operator. The actuator mounts through a 22 mm panel cutout and secures with the appropriate contact block module. Do not overtighten the mounting nut, as damage to the panel or operator body may result.
