I want to use a Radio Shack piezo buzzer as a doorbell. Data: 6-16VDC 65MA Two Tone. However, when I connect it up, it won't shut off. That is to say as soon as I connect the wires it begins sounding. I would be very grateful if anyone would take the time to tell me why this is happening. I also connected this piezo buzzer to a brand new doorbell button and a nine volt battery and the same thing happened. It appears that the current is jumping the two screws in the doorbell button.
