You'll have to use a certain teleport to find it.

It's pretty easy to do, really. First, place a teleport, it doesn't much matter where it leads to. Next place a switch at the place that teleport leads to. Finally, place another teleport on top of that switch. When MM goes over the first teleport, it will look like he triggered the switch without even touching it.
