Just FYI. I happened to have a clickie switch from a Garrity 2AA, I think. It was just laying around and I don't have a Garrity light, so I took my dremel to it to get the switch out. Whadda ya know. The switch is a perfect fit for the G2. The rounded edges fit perfectly into the G2 body and comfortably rests on the negative contacts of the switch. The down side is that there's no momentary. Just on or off. If you have one of these switches laying around, you might want to try it though. The no mementary is pretty cool too, in the sense that the G2's don't lock out so there's less chance of accidental activation.
