Light Switches

There are 3 switches downstairs, each corresponding to one of the light bulbs upstairs. How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs?

    Turn on one switch, leave it for about a couple of minutes, and then turn it off.
    Then turn on the next switch.
    When you go upstairs now, you can automatically determine the switch of the light bulb that is already turned on.
    Then you can feel the other two light bulbs and the one that is slightly hotter is the first switch that you turned on.

    Couldn’t have explained it better myself!
