Expert Answer:

 
These are the four possible configurations of the dual control switch
 
In ON state you will find the circuits is complete and current can follow through bulb
 
In OFF state you will find that the circuit is incomplete and current cannot follow through the bulb
 
Such switches are used in a place near the entry of room and near the bed or near another door (exit)
 
So the appliances can be controlled conveniently
