Mini Magic Switchboard

Each colored switch will only operate its matching colored bulb regardless of the position of the bulbs. You can even change the colored switch caps and still, they'll always light the matching bulb. The spectators can decide the position of the bulbs and the switch caps and even flip the switches. Yet, each switch will only operate its matching bulb. It's an impossibility. The bulbs, the sockets, the switches, and their caps are all perfectly ordinary and their examination will provide no clue to the method. All the trickery is built into the beautifully finished walnut board. Very good condition. As new and no longer available.
