Below is reply from Federal Office of Migration, Switzerland on my query

Dear Inquirer

Schengen visas are accepted in conjunction with a valid travel document for entry into Switzerland. If not otherwise noted, the Schengen visa is valid for all Schengen member states.

If you do not plan on travelling to Norway, we do not advise you to try and use this visa for entry to Switzerland as you may be denied entry at the airport.

The authority responsible for issuing the visa is the embassy of the country in which you plan your main stay. If you are travelling to various countries, it is the embassy of the country that you plan to visit first. If you have no intention of visiting Norway and are planning a visit solely to Switzerland you would thus need to apply for a new visa at the Swiss embassy.

It does not matter which airport you arrive at or depart from, providing you stay no longer than 90 days within 180 days in the Schengen area. The number of entries applies to the whole of the Schengen area and not just to individual member countries (if not otherwise noted on the visa). Therefore you may travel throughout the whole of the Schengen area on the same visa for the duration of its validity.

For detailed information on entering Switzerland, please go to: http://www.bfm.admin.ch/bfm/en/home/.../einreise.html.

If you have any questions, please contact the Swiss Embassy responsible for the area in which you reside: http://www.eda.admin.ch/eda/en/home/reps.html
