There is a big round cake with 7 candles along its edges. You must extinguish all 7 candles that are placed in a circle. The rule is: once you blow out one candle, the next ones go out too. If you blow out an unlit candle, it will light up again. So if you blow out a candle, it goes from lit to unlit and vice versa (just like the candles on either side). How can you blow out all the candles in the least number of times?

Tip: blowing out the same candle twice is the same as not blowing at all. Blowing the same candle 3 times is the same as blowing it once.

You can press the switches any way you want, but once you open the door, you won’t be able to touch them anymore.

Which switch controls the light?
