Thanks for the fast response!
I haven't been through the entire dungeon just yet but here are the areas that I am having a bit trouble with:
The first set of switches is located in the middle of the west side of the map. There are four switches and there is also a sign nearby that reads "A little help: 3".
The second set is in a hallway at the bottom of the map. There are a bunch of switches on both the north and south sides of the hallway, each switch has a number next to it (1-13). There is a sign nearby that says to ask Norbert if I don't know what to do with them. I don't believe I have found him yet.
Thanks again for the help
