Robust Big Piezo Button

The buttons have an impulstime of 0,7sec. I decided to change the 56k resistor R4 against a 10k resistor. Now the impulstime is 0,1 sec.

Here is the button mounted in the wood plate

I placed the 3mm Led on the backside.

It was easier to see the light of the Led from the outside than from the inside :)

I used 6 of these buttons here:
