He flips on switch 1 and 2 and does nothing to 3. He waits a minute or so, then flips switch 2 off. When he enters to room, if the light is on he knows it is switch 1. If the light is off, but hot to the touch, he knows it is switch 2. If the light is off, and not warm to touch, he knows it is switch 3.
