Thank you SoCalDep, I couldn't have asked for a better response. I will be, as I'm sure many others, very interested in this solution for the DG switch. It does seem like the DG switch can be a very useful tool when the goal is to not keep the light on at all times.
I find that while shooting the light is always coming on as I put pressure on the grip. But I assume that in a shooting situation a light coming on is not going to be a big deal.
