- Hermione knew quite a bit about Switching Spells already in her first year, and gained some house points for it from McGonagall (PS9)
- Neville wasn't particularly adept at these, managing to switch his own ears onto a cactus during Transfiguration class (GF15).
- Hermione, discussing ways to combat dragons:
"Well, there are Switching Spells...but what's the point of Switching it? Unless you swapped its fangs for wine-gums or something that would make it less dangerous..." (GF20)
- The definition of Switching Spells was on the theory portion of the Transfiguration O.W.L. that Harry took in June 1996 (OP31)
