milliamps for switch?
I'm playing with the idea of a pipe mod. Driving people insane on another forum about it. Biggrin I like the idea of a small momentary micro switch on the side of the bowl better than the magnetic push button. Does anyone know what kind of milliamps are being drawn from a 18350 with say 1-2 ohm coil?

RE: milliamps for switch?
2 ohm coil - volts = amps x resistance

So 4.2 = amps x2

Divide by 2 to get 2.1=amps

At one ohm 4.2 amps

This is with a fully charged cell. So you want a switch capable of about double those numbers to give some margin.

Thanks Don. Wow, I never thought it would be anywhere near that much.
