AK Selector switch

Is there a difference in the AK74 and 47 selector switch?
I have several different arm profiles--some clear the trigger, then some need filing to fit.

Not really.
The axis pin holes and the selector hole are in the same relationship in the receiver.
The differences in fit are because of differences in fire control and how much the selector may have been clearanced before you got it.

I have run into selectors that barely keep the trigger from releasing the hammer and others that will barely go to safe.
I have also welded up a few selectors to extend them so that there is not so much trigger movement while on safe.
