Horn switch wiring

You don't say what flavour of Spitfire you have, but for the pre-1500 Spitfires you should have one wire that runs up the steering column and attaches
to the bottom of a copper(?) ring, visable when you remove the steering wheel it's self. Nothing in this part of the loom shoud be moving - regardless
of how much the wheel turns, so chaffing shouldn't be a problem.
In the centre of the wheel you should have the horn button. This has a contact that presses against the metal of the wheel hub (and from there to earth). On the bottom of the horn button is another metal contact.
Inside/under this you should have the central hole for the steering column splines. Around this is a ring of metal with a hole through it in one place - about 1cm diameter.
There is a special 'thing' that pushes through this hole, and makes a contact between the +ve copper ring and the non-earthed contact on the bottom of the horn button. This is basically a length of clear, rigid plastic tube, with a two metal contacts - one at each end. Between them is a length of wire, in side a spring.
Any help?

The problem is resolved. Apparently a previous owner has fitted another steering wheel that will not accept a central horn switch! My fault for not knowing what the original wheel looked like. Thanks for your responses, and my apologies for wasting your time-

I know you said it was sorted, but if it's a 'common' type - Moto-lite or Montney(?) as it looks, you might be able to buy a correct boss (the black bit that goes over the splines) for the spit (with horn hole) and not just that one which fits the splines. It's just a matter of unscrewing the silver screws from one boss and onto the new one.
Oh, and BTW, I can see why the wires would chaff on that setup!

Mark, wow fast response or what? Your decription although precise, does not seem to relate to my 1200 model. I do have some pictures I could send you.
If you would like to view them, contact me at david.f@virgin.net and I'l send them. (No sweat if you don't)
