Your design is great in concept but has one major flaw. you failed to for something getting between your contacts, for example a real rat or feline pet.
dont use it if your so worried about it idiots these days!!!, gosh!!!
I used mouse traps to train my dogs to stay off the living room furniture. I showed them a "set" trap a couple of times, springing it each time (SNAP!) Believe it or not, they learned to tell the difference between a "set" trap and a "sprung" trap so they were not deterred if the "sprung" trap was placed on the cushion. I used "set" traps when I found this out. Got my wife a couple of times - ha ha. A nice loud alarm would probably be funny but might get me divorced.
Thanks for sharing - I learned something cool today :)

Hahaha...this would be a great prank!
