Steering Column Light Switch Rods

The pic above shows an original unrestored 1932 chrome plated light switch handle.

The table below shows the Ford part numbers and lengths for the various Model A style steering column light switch rods used on 1928 through 1940 Model A, Model B, and later V8 cars and commercial trucks.

The original light switch rod assembly consisted of a nickel or chrome plated die-cast aluminum handle swaged onto a terne plated tubular steel rod. The horn circuit ground wire was inside the rod, and an insulated contact terminal was at the bottom of the rod.

Light switch rods made from aluminum tubing are relatively modern reproduction parts. All originals were steel.

A keeper groove was located near the bottom of the rod, and a 'C' clip in the keeper groove retained the spring loaded spider which operated the light switch. (except for very early 1928)

The dimensional data below was compiled from Ford published Parts Price Lists and from original Ford drawings on record at the Benson Ford Research Center in Dearborn.
