Re: 833 lighting switch

All of the 8th series cars used the same light switch, a Clum 9170 and the switch was unique to the series, the prior 7th series using a Packard-made switch, and the 9th using a Culver-Stearns unit. Whether there is any interchangeability I don't know but the Culver-Sterns used in 1932 was model G-841-A. There is a wiring diagram including the switch on The Packard Club (PAC) website (select "Wiring" from the left side menu bar) and probably on this site as well. But the very best wiring diagram in terms of clarity on the switch is in the Standard Auto-Electrician's Manual of which I have a copy. But it is a bound volume and getting it to lay flat on a scanner bed is not easy or even possible. But if the other wiring diagrams don't do it for you, let me know and I'll see what I can do, perhaps a photo of the page.

These switches had very long service lives and thus there never was much replacement stock, you're probably going to have to repair your switch. The good news is that Clum switches were used on many makes of cars so you aren't limited to just Packard parts sources. In addition of Clum and Culver-Sterns, the other significant makers of light switches at the steering column base were Delco, Briggs & Stratton, Pines, and Soreng-Manegold and it's possible they made service replacements for each other's units. Wish I had some interchange info but I don't, hopefully someone else does.
