~ a year ago, I discovered a mint black AA MM (vintage early 90s?) sitting in a box, unused, and I expected it would remain there forever. Instead, I screwed an LITT tailswitch end cap on it, and it's currently sitting on the table next my favorite chair, and I now can enjoy using it on occasion purely for nostalgia. I did then also throw in an LITT LED module, which was a factor in its rescue, but it was the tailswitch that brought it out of storage. Just sayin'......
Yes, it has a lot of thread slop / 'wobble' in the head. I don't much care now, as it matters little since it's in one spot now with some Teflon tape to help keep it positioned correctly, since I no longer need to try to operate it with one hand using my arthritic fingers, much less "focus" :-( the dang thing! If I was picky I guess I'd bypass the stock 'switch' just to eliminate the contact resistance, but I'm ( just barely) able to set it appropriately for the new light source, so I haven't bothered.
I once used them a lot when I had few other options until my SL Scorpions came along (mostly two 3-cell conversions I had for some decent output), but now I can actually enjoy using one in this form. With a proper switch, it's a pretty cool light now. I don't give a rat's rear what TM might think about the switch. He can stubbornly keep using his stock if it makes him feel better (which I'm sure it does). If I'd made as much money on them 'stock' as he did, I'd probably keep using them stock too🙂
