Resistive touch switch
« on: October 13, 2014, 13:40:51 PM »

Can anyone help me with component values for making a simple resistive touch switch?

I am a drummer and an electrician. I studied electronics years ago but have never used it in practice, so although I understand how things can work, I don't know how to design circuits. I want to make a switch for choking an electronic cymbal. It simply needs to short the tip and sleeve of a plug to work. I want it to operate off copper strips on the bottom of the cymbal so when I grab the, my finger activates the circuit and turns on the transistor.

So what happens is - I hit the cymbal, it triggers the crash sound via a piezo mounted on the cymbal, then I grab the cymbal where the copper strips are and voila, the cymbal chokes stopping the crash sound - just as a real cymbal would do.

I refer to the wikipage - http://www.pcbheaven.com/wikipages/How_a_Touch_Button_works/

I hope to get this circuit to work for me.

Hope all that makes sense.
