Dimensions for Drill Hole to Install Mounting Panel for Redarc Tow-Pro Elite Brake Controller Knob
Question:
What is the diameter of the round part that is inserted in the panel? Not including the LED notch or the gripping pieces not the 1-1/8inch shown in the pictures. This would be the minimum size hole to drill in any panel on any vehicle prior to cutting out the LED notch section to ensure a snug fit so it wont spin in place since it would be held in place by the LED section of the switch.

The outer diameter of the smallest round part of # 331-TPSI-003 is 1-1/16 inches. That's not counting the tabs or the beveled section and is shown by the red arrow. I think that's what you're asking about. If not let me know.
With that being said at the top of that is a notch that makes it so the hole you drill may need to be larger. From top to bottom with the notch it measures 1-1/8, just like the tabs, and is shown with the yellow arrow.
