Schneider Electric ZB4BR2 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BR2 is a non-illuminated, momentary push-button switch with a 22 mm mounting hole diameter designed for industrial control panel applications. Featuring a round, extended mushroom-head actuator in black metal construction, this switch returns to its default position immediately upon release. Rated NEMA 4X and 13, it is suitable for harsh environments where dust, oil, and corrosive elements are a concern. Licensed electricians and industrial maintenance technicians install this switch as an operator interface device in machine control and automation panels.

The ZB4BR2 fits standard 22 mm cutout operator stations and control enclosures commonly found in manufacturing, process control, and heavy industrial environments. The extended mushroom-head profile provides a large actuation surface, making it well suited for emergency-stop-style mounting positions or high-cycle operator controls on automated equipment. Its metal construction handles the mechanical demands of continuous use in commercial and industrial facilities.
