I just got my Arc4+ today and absolutely love it! I have a question regarding the operation of the tail button. I was curious about the click the light made when the button was pressed, so I clicked the tail button repeatedly in complete silence. It seems that on my Arc4, when I push the button fully then slowly release, there are two "stages". There is the initial release of the button which makes no sound, then just before (and I mean literally just before I release the switch) there is a slight "click" as if there is a small micro switch that is released. Does this make any sense? It also seems to be more noticeable when I have clicked the button continuously for a while. Keep in mind that the switch works fine, I'm just curious if anyone has listened to their light when they click and release. Thanks.
