You have to use custom graphics and NPC codes, but that's not that hard to do.
The difficult part is the fact that the on/off state of the switch won't permanently translate to the rest of the levels, which is why you need to come up with some pretty abstract/weird ideas to work around it. This is why people are suggesting things like multiple world maps (that won't work but it has the right idea behind it).
