Schneider Electric ZB4BA7120 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BA7120 is a momentary push-button switch designed for industrial control panel applications. It features a 22 mm mounting hole diameter and a flush-mount, rectangular operator in black and white. The bezel is constructed from chromium-plated metal, providing durability in demanding environments. The switch operates in an On-Off sequence with momentary (MO) action, meaning it returns to its default state when released. It is rated for shock and vibration resistance, making it suitable for equipment subject to mechanical stress. Licensed electricians and control panel builders are the primary installers of this device.

This push-button switch is used in industrial and commercial control panel assemblies where a non-illuminated, momentary operator is required. It is appropriate for machine control stations, process equipment panels, and other applications requiring a NEMA 4X or NEMA 13 rated enclosure environment. The 22 mm body size is a widely adopted standard in industrial control components, fitting standard 22 mm cutout operator stations. It meets multiple international standards including UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1, making it suitable for both North American and international installations.
