IT does say illuminated , it also says it's rated for 125 VAC that means it's not going to light on 20 volts ... No way ...no how.
I think we already figured that out.
I'm not confused in the least. I see you didn't quote my full post not only saying that his switch wouldn't work at 20 volts because it's rated at 125 VAC AND the fact that I offered a solution . No but you did feel compelled to make some kind of dig in my direction with "I think we already have that figured out" and THAT is the way I took it or you wouldn't have said anything at all.
So if you don't like potshots don't make them. My post was in an effort to help the original poster while yours was to satisfy yourself.
If you didn't like my comment in return to it Tuff.
