Turn the first light switch on and wait 5 minutes, turn it off. Turn the second light switch on and go into the other room. The light bulb that is currently "on" represents the second light switch. Touch the next two light bulbs and which ever is hotter represents the first light switch. You can find the third by cancelling out the other two.
The original light switch was invented in 1884 by John Holmes. This switch was made to prevent "arcing" of the electrical circuit, and the design is still in use today.
