Here are some pictures of Kingston coil box switches.

Fist is a picture of two reproduction switches 1911 vs 1909. Notice the Mag & Bat are reversed.

Here is the original 1911 switch on the left. It is made of metal where the reproduction is made of plastic. There is also a height difference.

These are the contacts. Notice the reproduction contact does not look the same.


The back reproduction does not have a slot for the common jumper.

The arm is lighter on the reproduction and the knob is not the same.


Here is the cover.

Very nice comparison. Thanks for the interesting study.

Both the Kingston brass switch and the J-B switches are BAT-OFF-MAG. Therefore, when using these switches, the coilbox terminal connections that come through the firewall are reversed: the magneto connection is on the passenger side. This is confirmed by original Ford drawings.

What does the inside of the new 1909 brass switch look like? Here are some images of an original for comparison. The "key" is new; all else is the original.

brass-1

brass-2

brass-3

brass-4

brass-5

In 1975, Don Hess sent me a badly warped composition version of the same switch. I managed to straighten out the top and made three complete switches of this type.

composite-1

So far, I have been unable to determine when this composition switch was discontinued in favor of the one with the brass cap or whether they were used concurrently. RV, do you have an answer?

Here is the 1909 reproduction switch disassembled.
I would really like to buy an original switch.
