Switches and bulbs

In your cellar there are three light switches in the OFF position. Each
switch controls 1 of 3 light bulbs on floor above. You may move any of
the switches but you may only go upstairs to inspect the bulbs one time.
How can you determine the switch for each bulb with one inspection?

Answer:

Weird Lateral thinking solution:
1. Turn on one bulb for some time.
2. Turn off the previous bulb, an turn on a different bulb
3. Go upstairs, and check which bulb is hot (first switch), the bulb which is on corresponds to second switch..
