Back to the disassembled switch. This one has contacts in good condition, but there are two more - the contact between the button and spring, and the spring to switch base. These were both dirty.

Here is the dirty horn contact. The switch contact itself looks pretty good. But the switch depends upon good contact between the spring to button and spring to switch base too. The spring contact surface could use some improvement

Cleaned up horn switch contact. Clean the switch base and spring while you are at it.

With everything cleaned up, your switch is ready for reassembly, here's an exploded view.

There's a small assembly trick, when the horn button and spring are installed, it is very difficult to get the switch rear contact to slide into the housing.

I have used a small drill bit, a piece of piano wire (get this at a hobby shop), but the easiest tool I've found is a narrow shim, like a scroll saw blade. Use any of these items with the little weep hole in the bottom of the control housing to depress the spring like this....

Next, slide the rear switch contact into the housing slots.

Pull out your assembly tool, and your job is almost complete

Just, install the turn signal switch, and install the bolt and washer.
