Solution to puzzle switches controlling individual lamps

By adding 4 diodes in parallel to the switches and lamps you can now control each lamp from its switch above.
As it's an AC supply the diodes direct current to the appropriate lamp by bypassing the other on it's particular half cycle when a switch effectively shorts it's corresponding diode.

Would be interested to see the solutions that were suggested using fewer components, please post them as intrigued how it could be done with less.

Before your hints I was sure that it had to be done with diodes. My one component solution: a single diode with it's anode connected between the switches, and cathode tied between the lamps. This allowed individual control, but it was flawed in that the first switch Had to be closed to allow operation of the next lamp. It was fun to play with though and I hope some other beginners gave it a try too. Thanks for sharing.. :^)

Glad you enjoyed it, if I find anymore on the net I'll post them. If anyone knows a solution using less components please post the circuit.
