Touch sensitive switch?

I'd like to replace the cheaper looking normal push buttons with something a little fancier. I've seen some touch sensitive buttons but they seem to require controllers and such. I don't have any spare arduino pins but I thought touch buttons were fairly simple but can't find any to buy?

One way you could skin that cat is get a Qtouch eval board from Atmel.

Piezo switches ain't cheap.

Otherwise capacitive switches, Digi-Key doesn't seem to stock them. Both kinds are basically weatherproof anti-vandal switches. Anti-vandal switches typically cost $50 per. That model I just linked you was the most cost effective available.

Otherwise you can glue a piezo disc buzzer to something and it will give off a signal when pressed.

Seems like a little context is missing.

Capacitive / touch buttons tend to be integrated into a mechanical structure. So it is not common to find a "touch sensitive button."

This might be of tremendous help to you:

Or a simple nand and nor logic chips and have two separate "touch" sensitive channels that latch on and off with the output separate from the arduino or just the nand and have 4 buttons you can hook up to the arduino, just needs some resistors and requires physically touching the metal "button" which could be anything conductive,foil or wire whichever
