Could I use metal buttons as a capacitive button for my arduino project?

Question

Could I use something like this as a capacitive button for my arduino project?

Would that make that button a capacitive button? Or am I totally barking up the wrong tree here?

Thanks :)

What type of wires are you going to use? Wearable design? You might be able to do capacitive button detect directly without the module. Use an analog pin and a 1-10 M resistor, and some software. tuomasnylund.fi/drupal6/content/… — Mikael Patel, Commented Jan 21, 2016 at 13:30
I don't know. When I designed a capacitive button the IC I used required a metal plane with a dielectric, and you had to touch the dielectric (so you created a capacitor between the metal plane and your finger). Maybe there are other capacitive button controllers that require direct metal... — frarugi87, Commented Jan 22, 2016 at 15:16

Yes, that would work.

The only thing to watch out for is that the buttons might be plastic with a thin layer of metal on top (Chemical vapor deposition).
