Just to clarify, all the high/low A2 twisties I own have experienced NO problems at all -- just yet. I take effort to clean and lubricate the internal tailcap chassis whenever possible. However, having known of such tailcap's problems, I decided to procure a few more just in case. Unfortunately that was the time when SF stopped issuing many legacy parts, including the A2/L replacement tailcap, so I ended up purchasing a few used ones on eB, in various conditions. (I only acquired the A2 back in 2019.)
So, as you can see, when SF tailcaps fail then you're pretty much on your own now. And that's one of the reasons I've sold off my Z48 and SW02 tailcaps, because I can't service them myself in case of failure. I now stick primarily to the Z41 (and Z57/61) McClicky mods for SF light setups as this is the only user-serviceable tailcap config. So do take extreme TLC to your tailcaps, especially the two-stage twisties.
If a tailcap switch has resistors or more complicated electronics inside then at some point they may fail after prolonged use. Keeping the chassis as clean as possible may prolong their lifetime. I recommend DeOxit Gold (G100) for conditioning tailcap chassis.Oh, I see.
I have actually use/d the L2, EDCL1-T, and EDCL2-T for work, without any problems with the tailcaps, ever, with multiples of each.
My first L2 use was in approx. 2005 or 2006, when I found they worked very well for me.
Another L2 soon became a nightstand light for me.
Thanks for the suggestion on care of the tailcaps, I think I'm good with that, but thanks again.
Did I mention I actually use/d mine, at work and at home, with absolutely no problems, since 2005 or 2006?
My experience with them may not be as long, or as hard use as yours, but never once have any of them failed me, or anyone else that I am personally aware of, that carries/d them.

But even if your two-stage switches are still in good shape, one thing may still fail: the rubber boot. Once it's aged out and hardened, or when the knurling wears out, it will be at your best interest to replace it. Fortunately Lumens Factory does produce high-quality replacements if you need it someday.
Michigan does, and I bet more than half the States do as well.Sorry OT again, but which states still allow for those hi-cap mags as of date?
