I will move this from the other posting. I cannot get my horn switch to work so I am changing my car to the headlight horn switch. I will not use the headlight portion, but I was wondering if this is the type of switch my car might have had?

Mac's states it is for 1918-1922. My car is titled 1919, but it should be a 1920 touring if you go by the VIN on the motor.

Was this switch put on just some of the cars from this period, or only certain models?

If your car is non-starter/generator, it is correct.

Headlight/horn switch was introduced in the fall of 1918, a few months into the model year. It has two "on" positions and was used in conjunction with a dimmer coil since the lights operated off the magneto.

It was used from 1918 through at least 1921 model year non-starter/generator cars. Some folks say through 1922 model year. In any event, when Ford quit putting the ignition switch on the coil box and moved it to the instrument panel for non-starter/generator cars is when they eliminated the combination light switch/horn button.

(All 1918 models were non-starter generator.)

1919 forward they were on non-starter generator roadsters, tourings and, I believe, TTs.

In this thread is an early 1920 touring that my dad bought from the original owner in 1952. It has a September 1919 serial number. It is a non-starter/generator car and had a combo horn button. Note the kerosene lamps. The car is still in the Twin Cities.

Body number MAY (or not) help to date the car.
The engine may have been changed. :-)
Wait, what's wrong with your horn switch? Never played with one.
Others are far better than myself at the fine points here.
Erik types way faster!

Buy yourself an original or reproduction parts catalog for your car. That will answer many of your questions.

Looking back at this thread, realized I made a mistake.

Should read:

Headlight/horn switch was introduced in the fall of 1917 (not 1918), a few months into the 1918 model year. It has two "on" positions and was used in conjunction with a dimmer coil since the lights operated off the magneto.

I have both the steering column headlight switch and horn button and the dash mounted headlight switch and the key/ammeter.

The dash switch is hooked up and the column mounted switch only works the horn.

I must have an early steering column and being a 1919 with starter and generator so needing the ammeter and key/switch.

Do you suppose it was a left over column installed on an electric car?

just askin'
