I accidentally welded the tailcap switch of my Seraph SP-6 in the ON position a few weeks ago (shorted the 18650 for a second with the P60 spring), and though I`v replaced it with a new one, I`m gad I kept the old one to use as a twisty! the C01S (although a great little light) wasn`t ideal for All my needs this week.
I hope it`s not cheating though, it`ll only work now as a twisty and clicking the button does nothing at all because it welded shut. :shrug:
