Come on you tool lovers out there. Has anyone heard of the device I described on the subject line? Anything close?

Thank you so much! I was hoping for a How-To if a simple device was not available.

I just remembered something else which can remove the requirement for soldering.

A breadboard is a prototyping board where components can be plugged in and wires used to join different areas and make circuits. It's common in kits for kids to learn about electronics but could also be used for a long term solution.

If you went to an electronics store like jaycar, and said " I'm looking to make a project where a plug pack holds open a relay open so when the power goes out and it closes to complete a battery powered circuit with a buzzer" then they should be able to sort you out with something.

And on second thoughts you do want a resistors between the plug packs and relay and the battery and piezo. If you don't then it could use up more electricity to run.
