Hi Yoocp--one side of the atomizer has a hole to put the cartridge in and on the other side there is a small hole where you thread the battery into and it always air to to trigger the pressure switch in the battery or passthough? Please specify what model you are using.

maybe you mean the small hole on the 901 atomizer - normally you don't touch it but some cover it up during a drag with finger to make a harder hit?
