Nardi Deep Corn horn button
 

Does anyone have a Nardi Deep Corn steering wheel? The button that was supplied with mine is the metal one and I can't get the horn to stop sounding because the button itself is constantly grounded, so I'm looking at getting this plastic horn button but I wanted to make sure it would work first. Thanks!

The metal button in the main pic is the one I have right now, the Type A button is the one I'm looking at. I assume it works but I want to make sure before I drop $50. Also, if anyone has that button, is it dual contact or single contact?
