I have one of these. My solution to the problem is pretty ghetto, but it works really well. I use a rubber band and two wires with bare ends. They are tied to those metal pads pretty hard and never loses contact.
But if you are building something serious, don't get tempted making it easy for you. It gets worn out pretty easy, and you will have to get new wires, it's hard to put on and of and such.
[edit] Naah, if he has one of those pictured above, then the pads can't be folded in any way. They are quite solid. :/
