Mech mod with magnetic switch touch of a finger no push?

[DraganPDX]

Ive seen this before where the mod had a switch at the bottom that required just a touch of a finger no push, anyone know which mod has this feature?

Doesn't sound like a mechanical mod to me.

Some mechs can be adjusted so finely that they seem to have no button movement at all.
I have a Vapoart GP PAPS with a 0.45mm (0.018") throw requiring very light pressure. Unless you're used to it, you'd swear the button doesn't move.

There is a touch and/or motion "sensor" button type mod... and although it looks like a mech, by the fact that it uses an electronic button, and that it's actually a regulated APV, it's not a mech. That is the Aerovapes "Aero S".
