1966 Optional switches: Rear Air & Hazard flasher. (I need info)

The original hazard switches are a special oddball. They are 4 terminal, all open when off, all 4 connected when on. One terminal is incoming power from the hazard flasher, one terminal goes to right front, one to left front, and last one to brake light switch line running from brake switch into column turn switch.

You can duplicate that switch action with a common single pole switch and 3 rectifier diodes, say, 5-10A and at least 24V PIV
