I think i read that the first few runs of PS
mods had electronic tact switches, and the owners of those seem to be ok. I wonder why the decision was made to make the switch mechanical?
So many people were shorting out the tact switches for a number of reasons,
Overtightening the attys and crushing the little rubber grommet out of the bottom causing a direct short.
Flooding the attys and causing a short with the juices (I actually bought a unit out of the classifieds that when i got it, I had to boil the adapter to get the gunk out)
Having an atty go bad on it's own and causing a short..
Anything that shorts out the switch for more than a second or two causes the internal contacts to arc closed or to the post and break which = Bad switches.
The little tacts were never designed to be used in an application like this or take that kind of current..
Once I went to cartomizers I never had another issue. My GF still uses her Protege with the tact switch and prefers it over the mechanical switch.
I have the mechanicals on both the V1 and the fist run Protege's.
Still have the tacts in a bag, even have the resistored tact switch for 5v..
I just prefer the feel of the mechanical..
