If switches are numbered 1,2 & 3
First put on Ist switch & switch it off.
Now put on the 2nd switch and enter the room, check
If bulb is glowing, if yes, then 2nd is the switch if not
check if bulb is somewhat hot,then Ist is the switch
If both the above condition doesn't satisfy,then 3rd is the switch
