Eaton Cutler-hammer E22NB3 Illuminated Push-button Switch

Product Description

The EATON CUTLER-HAMMER E22NB3 is an illuminated, momentary push-button switch designed for industrial and commercial control panel applications. Built with a flush-mount, round green plastic operator, it fits a 25 mm mounting hole and activates only while held - returning to its default state on release. Electricians and panel builders install this switch in machine control enclosures, operator stations, and process control panels. It carries a UL Listed rating and meets NEMA 12, 13, 3, 3R, 4, and 4X enclosure standards, making it suitable for wet, dusty, and corrosive environments.

The E22NB3 is well suited for use in industrial control panels, automated machinery, and HVAC equipment operator interfaces where momentary actuation and visual indication are required. The green illuminated operator is commonly used for start or run functions, allowing operators to confirm circuit status at a glance. Its 25 mm hole diameter fits standard 25 mm cutout panels widely used in North American industrial installations.
