Mercury Key Switch - Panel Mount

[MNhunter1]

I understand most key switches utilize a 3/4" or 7/8" cutout. I am mounting a key switch to a center console and utilizing the the panel mount cover/switch mounting plate. Does this require a 2-1/16" cutout? I can't see any other way to do it.

I'd definitely 1st try on some scrap aluminum but I think you want to match the outer diameter of the inner flange of #7 on the parts breakdown.

2.046 = 2-1/16" cut out. That's the direction I was headed, just wanted to make sure I was on the right track. I have a little over ~1" of material to go through with the aluminum console and 3/4" plywood backer/dash panel. Looks like I'll have just enough length to secure it.

so my CMA statement, "test on scrap aluminum 1st" since I'm going completely off of your drawing and have zero experience installing this"

the cutout in the backer will have to be a little larger to accommodate the retainer (#3).
