I have a resistor per switch, but these are tiny (1/2 watt) resistors that
just make the speed control lever into a clunky potentiometer that sends a
control voltage to the solid-state controller. The only high-power
components now are a circuit breaker on the batteries, the controller, and
the motor.

with 7 micro switch combinations and 3 resistors, do you use various
series/parallel combinations to get more than 3 speeds ?
