Weird. Had the same thing happened to me the other night with my SS Turtle Ship. I locked the mod went up to check on the wifey and baby. Held him to sleep for 15 mins. Came back down to see my other lil one. Something told me to go take another vape. Went into my room and grabbed the TS unlocked it and "BAM!!!!" Finger got burnt. "Dropped it like its hot!!!"took apart the bottom switch.
The positive pin derlin melted and pin was stuck on the Sony. Battery survived but pin did not. Out of TS for now. ;(
That sucks Weez, but I did get a good laugh at "dropped it like its hot"
Now you have me wanting to go whip that song out and get my " Dip it low, pick up slow" on 
Back to your Turtle Ship though
DAMN ... Go check out Fatdaddyvapes, he may have replacement pins that you can buy. Even if you don't see it listed, I would email him to see if he can help you out.

So good ...
Well its only a 1mm difference, its not really that bad.
