Schneider Electric ZB4BL7340 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BL7340 is a heavy-duty, nonilluminated push-button switch designed for industrial control panel applications. The switch features a 22 mm mounting hole diameter and operates on a momentary (MO) On-Off switching sequence, making it suitable for start-stop control circuits. The operator buttons are available in both green and red, with a rectangle profile and an extended (straight) or flush mounting option. The bezel is constructed from chromium-plated metal for durability in demanding environments. Licensed electricians and control panel builders are the primary installers of this device.

This push-button switch is suited for industrial and commercial control panels where shock and vibration resistance are required. The dual green and red button configuration supports standard start-stop or on-off operator interface layouts. With NEMA 4X and NEMA 13 ratings, it is appropriate for use in washdown environments, dusty locations, and areas where corrosion resistance is needed. It fits standard 22 mm cutout control stations used across a wide range of industrial automation and machine control applications.
