>> I have got Schengen multiple entry visa applied through Austria now. I want to travel directly to Switzerland first, and maximum stay in Austria. Is that possible? Is there any official link available to prove that?
Information on the official Swiss Federation website indicates that you can enter the Schengen Area through Switzerland with the visa issued by Austria.
"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.
The authority responsible for issuing the visa is the embassy of the country in which you plan your main stay (i.e. in general the longest stay). If you are planning a round trip and intend to spend the same amount of time in several member states, the authority responsible for issuing the visa is the embassy of the country that you plan to visit first.
It does not matter which airport you arrive at or depart from, providing you stay no longer than 90 days in any 180-day period 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.
Please note that Great Britain, Ireland, Romania, Bulgaria, Croatia and Cyprus are not part of the Schengen area and you therefore require separate visas for these two countries.
The Principality of Liechtenstein has been part of the Schengen area since 19 December 2011.
If you have any questions, please contact the Swiss Embassy responsible for the area in which you reside"
The link for that information is:

Click the link "Special information on Schengen" and read the information under "Entry with a Schengen visa".
I would check with the Swiss Representation in your own country just to make sure. You can find contact details via the following link:
I hope this helps.
