If I were to run some twisted AWG#22 or such wire to the switches, with the intent to have them controlling solid state control devices, I'm wondering what the AHJ inspectors might think of that. Even if explained to them exactly what is going on (on the plans when permits are pulled), they might take the position that the next homeowner that buys the place from my estate might think the wire is OK to use after removing all the solid state and then wire it up as normal switch loops. So it might still need to be wired with AWG#14.
