A potentiometer is a variable resistor and in the case of the 41-220 is part 30 in the schematic. See: https://philcoradio.com/library/download...20Book.pdf
The on off switch is part 16. In many sets they are combined into one part. I’m not sure what the case is in your set.
In any event resistors can be used in both ac and dc circuits. The thing that limits their uses is the amount of current they can carry. Same with vintage on off switches which are simply a mechanical device that opens and closes a connection. Hope that helps.
