Take off the battery positive light bulbs, light bulbs were followed by a wire the other end of the battery anode, so that light bulb lit up. Then draw a line between the battery positive and negative electrodes of a switch, causing a short circuit to open switch is not lit the lamp, switch off the circuit the normal light bulb and bright.
