I had one switch pad not working located above the dinner table, figured it probably was a bad connection as i could operate some of the lights from other switches in the coach. Gathered up the tools to get at this thing, so on my work bench was a paint can opener from Homedepot looking at it I wondered if the hook end would work on these hard to pop off covers. This thing worked like a charm, I did it twice just to make sure.
And it was the plug in connection causing the problem, put a little spray cleaner/lube works like brand new.
