WD45 Light Switch Options

The light switch on my WD45 is completely rusted solid, can I replace it with a standard automotive toggle? I know it is supposed to control the generator charge rate as well as the lights so I'm wondering what my options are. I know reproduction switches are available from Steiners and a few others south of the border, but I would prefer to find something local if it will work. Thanks. Richard.
 
I should point out that I'm still running 6V Positive ground type system, and much to my surprise the charging system is functioning just fine. If I put in a standard auto toggle light switch will I need to replace the genny cutout system in favour of a regulator? If anyone has been down this road already please speak up, Cheers.
 
If the light switch is rusted solid and the generator still works fine I would leave that just as is and wire separate toggle/Push-pull switch to a hot power terminal such as the Amp gauge terminal to run the lights. Gauge should show discharge when lights are on/engine not running and plus charge when engine is running and generator is charging.
 
Thats a good idea Charles, I hadn't considered leaving the old switch to control the generator and running a secondary just for the lights, i may just do that.
 
My WD-45 had a light switch that works fine but the Engine is a Gleaner-E Engine with a 12 volt generator w/ modern Voltage Regulator so the charging system is not using that switch at all but the lights are. Sometimes they can be freed up with spraying penetrate oil front & back for a while. I do have a John Deere with original light switch and switch adjustable cutout that still works. Nice to have stuff original but anything that old may have some upgrades?? cleddy
