Review on 🔑 Reliable 66706-55120 Ignition Switch for Kubota B5100 B6100 B7100: Enhance Performance and Safety by Reggie Hobbs

The switch is numbered 50, 19. 17.30 on the back and you can identify AC (accessory). If you're trying to find info on the numbers, it says to contact the manufacturer. That's no help. Others say trace your wiring to confirm what source it is like battery, accessories etc. Wouldn't it be great and less time consuming to just tell what the numbers mean? Other switch manufacturers use BAT, AC, IGN, etc.
