Button amp rating question

[Sedateme]

Got a quick question regarding buttons and amp ratings. I'm looking at putting together a simple VV box using the OKR T/6 regulator. I love my dual coils, and at 6 volts this is going to push 4 amps. Is this a straight spec as far as the switch is concerned? Do I need to find a 4 amp (or more) rated switch? Most of the specs list amps@voltage... ie 2A@14V, or 3A@12V... does the lower voltage in this system give more headroom where current is concerned?

If you use pin 1 of the OKR converter you won't need to be concerned about the amp rating of the switch.

As Mamu said, the button works on low current logic voltages. It applies a high or low voltage to the regulator to tell the regulator to turn on the output to the atomizer coil. Typically, switches in logic circuits have something like .1 amp ratings because they pull virtually no current ... just a signal voltage. The regulator carries the heavy load using a MOSFET to switch the output.

You might want to Google the spec sheet for the regulator chip to see the theory of operation and typical circuit usage.

That's a good choice. The OK-R T/6 will easily handle the 24 vaping watts

Here's a schematic with using Pin 1 with a low amp switch - http://www.e-cigarette-forum.com/fo...coolgate-variable-voltage-mod-coolgatesch.pdf

If using Cape's schematic, make sure you use a 10K ohm resister for R1, not a 100K ohm. Cape used the OKR-3A version which needs the 100K ohm resistor wired to pins 1 and 3. The OKR-6A version needs a 10K ohm resister.

Thank you everyone for the replies.

I should have done this before I asked the question. Thank you for the explanation... I'm not an electrical engineer by any means, but I have dabbled a bit. It was just quite a while ago and I'm shaking out the cobwebs. Going to breadboard all of this out before wiring it into a case. Using diagrams and knowing the "what" is great, I like to know a little about the "why" and "how" as well.
