Check out the Fourze movie. Lots of former Switch users show up in it.
Also, you have to remember that these are teens, and teens make dumb decisions based primarily on emotion. While you have to hold them accountable for their choices, there has to be some give (Additionally, the switches alter their judgment).

As for the switches, not counting the movie (Which made a point to use all 41), I think the only one that was used once in series was Medical (Maybe Camera, too). As for the hammer space thing, eh. OOO never explained where Eiji put the medals (More often than not, we see Eiji just insert new medals without being show him removing the first ones).

I'm glad you enjoyed Fourze. It's goofy and silly, and while there are some serious moments, it doesn't have a complete tonal shift and keeps the lighthearted tone until the end.
