Minnflyer, you never fail to impress. Thanks for the graphic. I see what you mean, In my mind I was imagining the very small switch that is already part of the light system which only has a throw of maybe 1/8"

The switch you show above would work very well. Also see the below thread I started in the electrics area regarding the ESC as a switch. It just may work as well. Just needs a little more experimenting.
