Confusing Switches

Question: You are standing outside of a room. Next to the door, there is a panel containing 3 light switches. One of them operates the light bulb inside the room. The other two do nothing when switched.

You need to determine which of the switches will turn on the light in the room. You may only open the door to the room once. There is no way to see any light without opening the door.

All switches start in the "OFF" position.

How do you decide which switch turns on the light?
