Button Amp Loads

[FaceT1me]

High guys I am pretty basic as far as my technical knowledge of electrical design goes.

I was wondering if anyone could recommend some sort of relay or mosfet that can be used in in unregulated mod to all me to use a 3 amp switch on a mod where the atomizer might be drawing close to 30 amps.

I am planning on building a dual 18650 wired in parallel and really trying to avoid melting buttons all day.

Bump, any help with this?

I am curious about this too. I was planning on building a dual 18650 in ll as well @ 30 Amps but I thought I would need a 10 Amp switch

Looks like some car starter buttons would work as far as amp load goes but man are they ugly and a little bulky

Here's some mosfets, most ought to do the job:

Could you point me at a diagram on how to wire it up, sorry not sure what to search for.

Also anyone know if this should work. i have been doing some reading and only thing I am not sure on is if the gate voltage rating is low enought for a 18650 battery to trigger it

The Rds-on is far too high. You'll be burning off tons of heat across it. This one is more than you'll ever need in every spec and is at a decent price to boot:

Thaks that looks perfect

Frys seem to stock NTE mosfets local to me anyone has one they recommend. With my super limited knowledge it seems like the nte2996 or nte2904 fit the bill.

Thanks for all your help and sorry for being so annoying
