Not sure exactly which measurements you are looking for.
First time poster here. Will try and answer. I'm currently using the information in this thread to put in my own functions on the auxiliary switches, so I just got mine.
The switches themselves sit on a base that sits in a little frame that replaces the frame on the Dodge RAM insert for the centre console, so if you have the Dodge Ram for the appropriate years, you have the console, and you likely have the RAM insert, and therefore have the approximate frame measurements.
The switches are mounted so they are in a similar arc to the centre console. I'm not sure of best way to measure that arc, but again, if you have the console, you have the arc.
The base of each of the 7 switch blocks (4 working, 3 blanks) is rectangular, about .95in by .8in.
The base the switches are set in is about 6.75 in by 1 inch.
That base is in the frame. It's so irregular, I'm not sure how to measure it.
Does that help?
I can't figure out how to upload more than one photo. Urggh.
