it just looks funny to me i guess ... i do know one thing for sure though i have bought 2 of there telescopic mods at about $50 each and found that there not a great build or design in my opp i think i could just buy a little higher priced mod and get one that i can depend on and know its going to last alot longer.. just my opp on the few smok mods i have owned...
I think that's what it must be. The switch moves the post down to contact the cap in that socket. The o-ring or whatever it is assures that there's no contact with the switch at rest. The slot in the post would be to adjust for manufacturing variances. Just seems like a strange way to do it when the switch can ground directly to the case but, it is all mechanical. A lot of people are sold on that. The only thing that I can see that might possibly go wrong would be for the post to work it's way out a bit and make contact with the case while the button's not pressed.
I'm not sure exactly how the circuit is completed but my thought was the battery sits on the post that is isolated from the rest of the mod until the button makes contact and completes the circuit. After all this speculation it will be interesting to see how they work.
to me they look like you just get the battery to conect some way + to - and the dam thing works, don"t think there are any electronic boards, that why they are called machinacal, I think ,,I wished i would have gotten a provari for my second mod ,I would have saved money if I would haveI now have 9 diffrent mods,.............
