Is it possible to use a PCB pad as a button? I think of using it to switch on a curcuit that is only supposed to be enabled, when the user holds it in its hands.
As inspiration, I used the pads that are being used on soft touch buttons on keyboards or in calculators:
I know that the human body has a quite high resistance, so what would be an appropriate circuit to detect the touch input? Bare hardware only. I don't withantwant to use any microcontroller here.
