It just clips in. There is a small metal spring underneath. It fits in the recess behind the button on little tabs. They *can* come loose under the button, causing your issue. Once you get the button off, it will make alot more sense.[/quote]
As Tony said, it's easy to pop the button off. One thing I recommend is using a little bit of 600-grit sandpaper to clean the connections once you have the button apart. My horn buttons were very intermittent but worked perfectly after I popped the plastic button off and worked over the metal bits with some very fine sandpaper.
