Now we have person A with B's consciousness and persin B with A's consciousness. That's one switch made. The light bulb is on. Now, they trade again. That is another switch, 2 in total. But the light bulb is off again. Now imagine 3 people - A, B and C with their own consciousness. A and B trade, that's one switch. A and C trade, these are 2 swtiches. A and C trade again, 3 switches. A and B trade again, 4 switches. Everybody has their own consciousness back, but still an even number of switches, so the light bulb is still off. And so on. In order for 2 people to trade their own consciousness and then get it back, 2 switches are needed between two same people. The machine allows only 2 people at the time. So for 2 people, it's 2 switches, 3 people 4 switches, 4 people 6 switces and so on. For 1 more person 2 more switches are needed. So the number of switches always stay the same - even. And since an odd number of switches are needed for light to stay on, it always stays off.
