saderdog,
If you only want to turn it ON and OFF, a good quality toggle switch will work. The heater blower motor doesn't draw lots of power.
Making the blower motor speed adjustable is another matter though. Slowing the motor from its designed speed by reducing voltage would require a rheostat, and it would have to be designed for the voltage and current application.
The specialty suppliers should have switches listed that were actually used on these rigs for the blower motors. Have you looked in the LINKS tab for folks that deal in Stovebolt stuff.
