Steering Column Light Switch Rods

The following table 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 was a nickel or chrome plated die-cast aluminum handle swaged onto a terne plated tubular steel rod. The horn circuit wire was inside the rod, and an insulated terminal was at the bottom of the rod.

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 early 1928)

The dimensional data below is compiled from Ford published Parts Books and from original Ford drawings on record at the Benson Ford Archives in Dearborn.
