More than that, I know there actually *isn't* anything wrong with it.

No, I will not. Why would I even be interested in a device that breaks the current in a circuit? A triac never does that! I only switches on in an active way. The current stops by its own alternating behavior. Nothing that happens in the buzzer when it breaks the contact has anything to do with a triac.

A 9 volt battery also has nothing to do with a triac.
