I've been trying to protect my battery from sticky switch.. so I maybe came up with a little trick.. if you take a thin layer of toilet paper, you can stick it in to the cartomizer from the battery end, roll it to make the tp piece like a little line so in case you over fill it the tp will soak up the e liquid. Make sure it is thin enough to still get airflow.. also you can just put tp piece in the middle of the battery and the cart and screw the 2 pieces in while holding the toilet paper in between.
Also I use a rubber piece for the battery.
Just a little trick I've been trying to use.. hope it helps.
