Awww. Well I'm glad there are people, however few, who do enjoy posts like this. I always like to post good Pokéart when I come across it.
What would happen if we placed the second end (without the spit) into the switch board and turned the switch on? Some kind of backlash of electricity?
Nothing. You'd just be connecting wires back to themselves. It wouldn't create a circuit, so no electricity would flow (assuming both receptacles are on the same circuit, which they would be in nearly all cases).
