I'm aware of an instance where the side switch of a Klarus G20 light sticks in the down position on odd occasions and may cause unintended and unexpected changes in modes etc. However, the rear switch seems to function perfectly, apparently.
I believe if the side switch is "worked" or operated enough, this might loosen the switch (in time) and eliminate, or at least minimize, the possibility of the switch sticking again(?) If this procedure doesn't seem to fix the issue, then the switch might have to be replaced? Or the switch might have to be looked at more closely and see what might have to be done to fix it without having to replace it?
Anyone else with same or similar issue?
