this was my first ‘mod’ if you can call glue and caulk that
After applying shoogoo on the flanges of the boot, and caulking the inside perimeter with marine silicone, press fitting the switch assembly with just 2 tiny dabs of epoxy (locations marked), it has worked flawlessly and was a regular user even in heavy winter rains until the D80 came along. I’m very satisfied with mine, the low cost is another pleaser.
