Steering Wheel Switches

[jb24 at chrysler.com]

There aren't actually slip rings.  It is more like a clockspring with a
large loop of individual wires that are just long enough to get the
steering wheel lock to lock.  Formula 1 and CART have just a simple coiled
bundle like a telephone cord so that the steering wheel can be removed.  Or
at least they used to - in more recent races I have seen some drivers toss
the steering wheel completely out of the car with no little umbilical.

I went to Las Vegas with the wife the last week of October.  Went to the
Sahara
hotel where they have an interesting driving simultation using 24, 3/4 size
Indy
cars mounted on hydraulic rams, each in it's on booth in front of a big
wide
screen.  You guessed it, you race against the other drivers.  For $8 it was
better
than the simulators in the arcades.  They give you a read out after you
race with
a traction circle and other info showing how you did.  After looking at the
info,
I was less frustrated and wanted to go back, but the wife had another
agenda.

The transmission was semi-auto with the up and down buttons on the steering
wheel.  That made me think of the higher end cars in the late '80's.  There
seemed
to be a contest to see who could mount the most buttons on the steering
wheel.  I
think the Bonneville SEi had more than an F-16 cockpit.  I know each button
didn't
have a seperate ring in the steering column, so how did the switch signal
travel
from the steering wheel to where ever it went?  All my electronically
limited mind
can think of is either different resistances or capacitances or varying
frequency
signals.

Am I close?
