Ohms law will calculate your amps. I = V/R is what you want. Amps or current is your I variable. You might want to consider a Mosfet for added protection instead of just straight wiring to a switch. At least this way you have a mediator in case something goes wrong. It is rather bad practice in any electronics project dealing with high currents to direct wire to a button of some sort.
Well it really depends on his vaping needs, I made a device with a 2A switch no mosfet because that was all it could supply so didn't need more. On other things I prefer to make a mechanical switch rather than using mosfet, but again that's me. But mosfet is the safest easy way to ensure that your switch can handle the load.

Wrong, but I like the way you think it's a 4.6V wired device so 2.3 Ohms minimum build, I did this more of an experiment than anything else and don't really use it although it is handy having something that theoretically can't fail.
