Can membrane keyboard switches respond to human touch?

Question

I need to know if those thin, membrane switches used for keyboards will respond to a funger's touch. I also need to know if i can DIY my own thin wires, again like on keyboards' membrane panels. I need a minimally evasive touch solution, and I think that using the same tech from the keyboard panels would be both minimally evasive, and give a bit of flair to my display. Also, if the switches do respond to fingers, can I buy them at relatively low cost.

Answer 1

No.

Membrane switches work due to mechanical action caused by a conductor that is pushed across a break in a foil pattern to complete the circuit.

Touch switches work due to capacitance that comes from static charges when our body touches the switch.
