As some of you may remember I recently had a tail switch start playing up on my TK10 (which has now been fixed) but during that time i was thinking "what would I do if this was an emergency situation and I needed it working".
Anyway, one of the suggestions to test it i found on here was to put a wire across from the body to the back of the battery, and sure enough it lit up, but it would sure be a pain to have to try and hold that there while actually using the light for anything.
So, the best thing I managed to come up with was a 4 layer thick (folded over) piece of tin foil over the end of the torch held in place by a rubber band. Put pressure on the foil, light comes on, take pressure off the foil, light goes off.
It wasnt perfect, sometimes the light was stay on and i would have to play a bit, but it was actually pretty good for an improvised job..
Has anyone else done this or something similar?
