Yes. You need a visa to Switzerland and not merely an entry. You will need to obtain information from the consular office to know what is required of you so as to obtain a Switzerland visa. Good luck.

You can go to switzerland if you've 6 months valid visa for the uk. But now its expired already, so you can't. I am afraid. Now you should leave uk as well.
