Questions about this item
Will the 22 mm mounting fit the existing panel cut-out on my older control panel?
The button uses a standard 22 mm mounting diameter, which matches the common cut-out size found on many legacy panels.
How can I verify the 1NO/1NC contacts are operating correctly after wiring?
With power off, use a multimeter to check continuity on the normally open and normally closed terminals while pressing and releasing the 40 mm mushroom head.
Does the package include the legend plate or mounting hardware, or must I order them separately?
The unit ships as a complete operator with the red mushroom head, plastic bezel, integrated Emergency Stop legend and screw terminals; no extra parts are required for installation.
