DIY Unlocking Bracelet

I'm looking for plans to make a set of bracelets that will unlock when they come in contact with each other (no keys involved). I'm not sure how to even begin looking for something like this, my searches have come up fruitless so far so I decided to take my request to the Instructables forums. Any help would be appreciated.

Possibly a magnet in one lifts a catch in the other?

I did not see this reply, but that is a great thought. Thanks for the input!
