hi midaz, its very clear that as of dec.12, switzerland officially bacame member of the schengen countries, meaning you can enter switzerland with a schengen visa. so as you stated before if you get a schengen visa , you should be able to enter switzerland.

ps.
take enough cash with you if you really wanna enjoy the time there. dont go now, wait for the spring and you will have more fun.

good luck and save trip.
