Yes PC hotas have actual mechanical switches and Sliding horizontal varible resisters which need grease to allow correct friction but are normaly lower resistance than a POT per axis...
The springs in switches that allow high speed clean contacts that don't exsist in console rubber dome switches, they do wear out but those switches are all the exact same pressure point and distance untill the switch spring is dieing... rubber dome are virable pressure right from the product release on every switch on the product there is no compliance for pressure compliance...
This is why the same controller batch has different rubber domes die at different rate from day one...
Interesting. I just assumed they used the "rubber graphite dome" as well. Consoles have used those since the original NES. Ive had to replace mine over the years though.
