Possible?

Think this would work? A vv/vw/mech set up. It would be made out of all brass.

There would also be plastic separating the positive switch, and positive pieces from the ground (housing)

That image is too small to see what's going on

 

[devlindchi]

is this better?

 

[dr g]

not really, it seems like the same size but cropped

Okay I see what's going on there, basically a VV with a direct bypass switch to the connector. I'm not sure if it would work per se but I'm thinking a PFET like mamu is using between the vamo board and 510 connector might help to ensure the circuits are isolated?

I was thinking about maybe adding a mini on/off switch, this way the vv circuit is fully disconnected from the positive side of the battery when being run in mech mode, then switch it on, press vv button 5 times and vape in vv/vw mode.

 

[devlindchi]

not from the battery, i meant from the "firing" rod

Yes. You've got to make sure the output (+) is never connected to the battery (+) on the VV/VW board. That would fry the regulator circuit which is likely not designed to take any input voltage on the output connection. In other words, you have to design a different circuit than you've diagrammed that will activate either the mech or the VV circuit independently and ensure that both can't be active at the same time, as well as disconnect the VV (+) output from the atty, when you're using the mech side.
