Porsche 911/912 Hockey Puck Horn Not Functioning

[azwildcats7]

Hi
I need a little help with my hockey puck Horn on my Porsche 912. The operation of the horn seems simple, yet doesn’t really make sense. I know when I contact metal between the "push toggle" shown in the box in red and any other part of metal on the horn receptacle, the horn goes off. However, tIt isn’t like pushing the hockey puck in is the same as the depressed action on a normal horn. The hockey buck horn really doesn't push in (other picture attache). I was thinking of painting the push "push toggle" with a non conductive application, only leaving the tip exposed, so that it could somehow make contact with the metal when the hockey puck is depressed with force.

I would really like to get my horn to work, so any help on what I need to do would be most appreciated!

Also, when I have it connected, it will just go off randomly, since I assume the metal of the "push" part touches metal to ground it out and make it go off. This is why I thought I might need to apply the non conductive layer.

Looks like the black rubber center is worn. They are available on the net for a few bucks.
