Someone explain Team Switzerland to me(What does it mean?)

Team Switzerland is Bella's team. It's her way of declaring herself neutral. She loves Edward and Jacob, and she's not going to pick sides. Switzerland was a neutral country in WWI, and so Bella is neutral when it comes to Edward and Jacob's feud. Team Switzerland is for those who love both Edward and Jacob, and don't care who Bella chooses to be with because they love them both.
"When it comes to all this enemies nonsense, I'm out. I am a neutral country. I am Switzerland." -Bella to Edward, Eclipse, pg. 143

Team Switzerland is what Bella is.she says she's Switzerland when Edward and Jacob are fighting.
I'm on Team Switzerland and Team Edward.

it means that you're both team edward and jacob

Bell used Switzerland, because this country try to maintain peace and not jump on someone's side, so Bella said in this way that she love them both and dosen't want to choose between them. I think, it's like that

It means you are both Team Jacob and Team Edward.You're for the both of them.
