I use a high quality two-contact momentary push button starter switch on my '32 and '40 from NAPA, O'Reilly etc, Standard SSB-1 or SSB-1. Commonly used on '37-'51 Fords, designed for 12V negative ground, but can be used in a 6V positive ground system by simply running one of the contacts to ground, as the switch body is isolated. One of the advantages is ensuring a good positive ground with a painted dash.
