Here's the battery card in the bottom.  The wires come down from the lights in the top and wrap around the card.  The card has a strip of metal tape around the battery and another separate.  The red wires are soldered to the battery strip and the blue wires are soldered to the other strip.  There's another little piece that you can push back and forth.  That's the switch.  It's covered with metal tape, too.  When it touches both the strips, the circuit is complete and the lights go on.  Move it away and the lights go off.
