Key switch replacement
 

I'd like to replace the the tired worn out switch on the 1200,
I think the previous owner used a small screwdriver as a Key,
So this one is a 5 prong Indak, But I only have 4 spades in the plug
From what I can tell the Factory switch should be a IH-61524-C3
which I think is a 4 prong. Maybe it got changed since 1976.

Is there a chart somewhere that shows wiring diagram on these different
switches?

thanks
Dave

New switches are labeled. Yes, the original was a four pole switch. Not really sure what you are needing to know? The switches are still available from CCC.... or you can get one from a parts store. Just make sure it is the correct one. These switches are super common and the correct one will just plug in. No wire "jockeying" to do.

To the best of my knowledge there is no chart for switches, there are however wiring diagrams in the tech section..

I'm not sure if this will answer you question or not but the NAPA number for the Quiet Line ignition switch is #7-01854 (thanks Lew). It is in fact a five prong switch but it works just fine (I believe the one that you get from your Cub Dealer is a five prong switch also).

Found one!
 

I called my local CC Dealer, and to my surprise he had several NOS
4 Prong PN/ IH-61524-C3 in stock, for $23
Plugged it in and works great.

I suppose I should try to support him occasionally, even if he is an Ass
