Friz - if I'm viewing the picture you posted correctly, you don't need anything new. You should be able to roatate it back into the correct position. My theory is this happens when you hold down on the switch after the window has reached the fully bottom position. There's no cut off on these power windows and you need to be really careful when rolling up or down that you come off the switch immediately when reaching fully up or down.
