What if the QR and KR, or QN and KN, or both are "switched" in the "identical position," is it still a draw by repitition? Please note, this isn't a trivial question, as the "position" is actually "identical," as we can't distinguish the pieces that got switched, except by tracking them. On the other hand, if they carry their identity through the game, then they are different.
FIDE rule 10.10:
-----
The game is drawn, upon a claim by the player having the move, when the same position, for the third time:
(a) is about to appear, if he first writes the move on his scoresheet and declares to the arbiter his intention of making this move; or
(b) has just appeared, the same player having the move each time.
The position is considered the same if
pieces of the same kind and colour occupy the same squares, and if all the possible moves of all the pieces are the same, including the rights to castle [at some future time] or to capture a pawn "en passant".

This is the definitive answer. Whether it is a QN or KN, KR or QR, etc., doesn't matter. The only things that matter are whose move it is, same kind of piece and color, and possible moves available.
