Schneider Electric ZB4BA26 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BA26 is a momentary-action push-button switch designed for industrial control panel applications. It features a recessed, round black metal pushbutton with a 22 mm mounting hole diameter and non-illuminated operation. The momentary (MO) action returns the switch to its default state immediately upon release. With a NEMA 4X and NEMA 13 rating, it is built to resist dust, oil, and corrosive environments. Licensed electricians and control panel builders install this switch as part of machine control circuits, operator interface stations, and industrial enclosures.

This switch is suited for use in both light industrial and heavy-duty industrial settings where a reliable, non-illuminated momentary pushbutton is required. Its recessed black metal actuator reduces the risk of accidental activation, making it appropriate for operator stations on manufacturing equipment, motor control panels, and process automation enclosures. The 22 mm mounting hole diameter conforms to a widely adopted standard for industrial control devices, simplifying panel layout and installation.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements and panel manufacturer guidelines. De-energize and lock out the control panel before mounting or wiring this switch. Use appropriate panel punching or knockout tools to achieve a clean 22 mm mounting hole. Verify torque on the mounting nut per the panel enclosure requirements to maintain the NEMA 4X and NEMA 13 environmental sealing ratings.
