that is the blinker housing it is attached to the column. the microswitch idea was to be installed in the steering wheel in my half awake half sleep ideas that won't work. I don't have a slip ring but was thinking of a way to make one work to use the original contact i was calling a button. I had thought of creating a thing similar to your cage idea with a ring that lays around the cancel cam on the back of the wheel and has 3-4 arms to depress it that are attached to the back of the horn button, therfore it would make contact with the ring/contact when the button is pushed
