Re: 23rd Series Horn Button

I believe that except for the chrome horn ring and emblem the other internal components are substantially identical to 41- 47.
Wes Boyer did a great job of illustrating that earlier assy and as he shows, there is no small spring to be seen. Using his drawing, I drew out the contact path and the wire portion of the contact should make a good solid connection to the round metal contact plate via the cupped edges of the center wire piece assy. Those two parts are the relay side portion and is kept isolated from the ground side via plastic and fiber insulators. The wire contact is retained in the center by a hollow plastic button like piece which the end of the wire contact fits into. A wave spring on the other side provides the tension so the grounded horn ring can rock approx 1/16" and touch the metal contact plate around the edges.
If the wire is twisting off I would also wonder about the stiffness of the wire. On the 47 it is very flexible -- almost like the typical soft wire used for voltmeter leads -- and should easily be able to absorb several revolutions without twisting off. A tiny bit of the wire insulation may also be crimped onto the contact which would lessen any twisting stress.
