Horn help

My horn hasn't worked since I bought the car so I bought an overhaul kit and pulled it to bits today.
I am certain that I have it all connected correctly, but it still doesn't work. If I screw it all together with the leg on the horn button contact not touching the contact brush in the hub, then the horn won't work.
If I bend the leg out a bit so that it touches the horn button contact, the horn goes (non stop) once I have the screws tightned up.
I can't make head nor tail of how it's supposed to work! Any ideas what I'm doing wrong?
