Piper Chuck... I've got some of those that you mentioned but I dont' think they are that easy to use. Although they are pretty with the aluminum finish on the switch, the charge isn't so easy to use. I would recommend something like this, which I've used with great success. It's slightly unsightly but much easier to use. Mine had a larger switch with a protective shelf to prevent accidentally turning it off but didn't have the LED lights. I have used it on several planes. It currently resides in my Lazy Tiger.
