Switch or pot, machs nix. Yes, it's slightly tapered so tapping it in wedges the taper into the stub. Very common with replacements. It allowed servicemen to stock less controls to cover more radios. For instance, there might be 7 different radios that all use the same control but with different shafts, short, medium, long, 1/4 round, 1/2 round, split, fluted, etc. Rather than having to stock 7 different controls he could stock one control and a selection of shafts. Now multiply that by all the different controls, vol (with or without power), tone, power, etc and you can see how much less controls were need to cover the same number of radios. Plus, if a customer broke a shaft he didn't have to replace the whole control, just the shaft.
