Draw the circuit for controlling on lamp from two different points.
Here two single pole double throw (two way) switches are used for control of one lamp from two different points. As shown in figure phase of the single phase supply is connected two lamps in series and neutral of supply is connected with the lamp.
Lamp will only glow when positions of both switch 1 & switch 2 is L1 or position of both switch 1 & switch 2 is L2.
If one wants to make the lamp off change the position of either switch 1 or switch 2 i.e. make switch 1 at position L2 or make switch 2 at position L2.
