Flush-mount pushbutton switch · 22.5 mm 1NO-1NC maintained non-illuminated black - Eaton C22S-DR-S-K11
What this product is for
This 22.5 mm flush-mount pushbutton switch is used for operator control on industrial panels, OEM equipment, and machinery stations where a maintained pushbutton is required.
Use for
Use for start-stop logic, machine control circuits, panel doors, and control stations that need one normally open and one normally closed contact in a compact assembled device.
Avoid for
Avoid for applications that require illumination, emergency stop function, or a momentary operator unless you have confirmed field conversion is suitable for the installation and local code requirements.
Best for
Best for electricians, panel builders, and maintenance teams needing a compact 22.5 mm operator with sealed front-of-panel protection for wet or dusty industrial environments.
Installed in
Typically installed in control panels, machine enclosures, operator stations, and industrial equipment doors with a 22.5 mm mounting opening.
Why this product exists
This model provides a ready-to-install compact pushbutton with integrated contacts, reducing assembly steps compared with modular operator and contact block combinations.
Compared with similar products
Compared with momentary pushbuttons, this maintained version stays in its selected operating state until actuated again. Compared with illuminated operators, it is suited where pilot indication is handled elsewhere on the panel. Eaton notes that maintained versions can typically be field converted to momentary by switching the locking ring. Confirm suitability before specifying.
