    Im trying to make the signal that a piezo puts out to also be the signal to close a contact.
    does anyone know how to build this switch?

    what im trying to do is, I have a drum machine that uses a piezo to determine volocity of what ever pad you hit!
    what I want is to have the signal from the piezo to tell a switch to close.
    this way the pads become so sensative and wont need to be hit so hard.

    Thanks brian
