Touch switch diagram anyone?

[Mrgreen819]

I did search first,this forum is huge. I imagine its here somewhere. I'm hoping someone can post a wiring diagram or schematic for a touch switch. Would be very appreciated.

check out breaktru.com index. Load of info.......

The key to using this circuit is the 10 MOhm resistor between the Gate (G) and Source (S) pins on the IRL3103 mosfet (I picked up some of these from eBay). You may have to increase the resistor value to get a good response. I ended up using 4 10-MOhm resistors in series (40 MOhm) to get a good response of the touch switch.

My one and only touch switch mod (that I built, I have a Saber Touch mod) - http://www.e-cigarette-forum.com/fo...79-finally-its-done-my-touch-switch-puck.html

Thank you both! I did not have any luck finding the ckt on breaktru's index but lots of great info there. The links are great thanks for that TomCatt. I also have been googling and learned there are like 4 types of touch switches. Some use a single touch pad, some a pair of pads and others use a pair for "on" and a separate pair for off. The single pad variety are the slickest but can not work in wide open spaces. Still reading will post my findings.

Here is a thread I did over a year ago on making a simple touch switch, and then went into designing a capacitive touch switch, maybe it will help:

hey Dan, I found a 'smiley' for ya

Thanks Dan! He always knows the answer to my questions. I found this and it explains the different types and pro's and cons of each. Touch Switch

Wow Dan you don't do anything without throughly researching it. I only read up to page 11. I thought I was through. Thanks again for the links guys answered all my questions and then some. Still reading and learning. It's been ages since I etched a board Dan. I once etched my own double sided board, fun project. Back then you hand drew your lines or used the rub on type of stencils.

Well nobody has the atmel AT42QT1010 in stock. Minimum 10 week factory lead time. I am so done with waiting so this is going on the back burner.

It's been said before but this topic should be stickied so people can find it. There are always people on ecf looking for touch switch designs.

I would like to know more about a touch switch setup. I want to build a copper tube mod using one.
