By experimentation I built the attach circuit for a touch switch. Over the copper trace I place a piece of conductive rubber (from the inner tube that is used on truck tires). When press the 4066 is activated. I notice that if I used a 10Meg resistor the 4066 is activated when the copper trace is touch with a finger but not with the conductive rubber place over the copper trace. So I increase the resistance to 30Meg and voila! the conductive rubber works to activate the 4066. Can you give me an explanation why it works? (I do electronics as a hobby).
Also can the 4066 be damage by using this type of circuit? My next experiment is to get the 4 switches in the 4066 to work with 4 corresponding copper/rubber sensors.
Thanks,
