The low charge, high charge rate switch was used on systems without a regulator, i.re. those with a cut-out relay. The regulator adjusts the charge rate to suit the state of the charge of the battery, when near fully charged, too large an input current will harm the battery. The high charge would be used immediately after starting, particularly if the starting process was protracted, to bring the battery quickly up to charge and then switch to low charge to keep it fully charged, or bring it up slowly in normal operating condition. If the lights were on the system is effectively in low charge automatically. If the is a voltage regulator then the switch position are lights off, dim and bright lights as the other features are controlled automatically by the regulator. The early systems used a cut-out relay, to ensure the current went from the generator to the battery and not in the reverse direction. The output control was left to the operator. IH apparently made the switch from cut-out relay to regulator in 1949. My 1948 Super-A has a cut-out relay on the generator.
