Switzerland is not in the european market,do the use and accept the euro as a currency?

The official currency is the Swiss Franc, worth about 65 or 70 Euro cents.
Most hotels, restaurants and large stores will accept the Euro. Many small ones will too (as will my babysitter), though of course they aren't obliged to. I'd say about half give back change in francs and half in Euros. You can also change money at any train station or take out money at any of the millions of bank machines. (Be warned: if you ask for 100 francs you'll get a 100-franc bill and if you ask for 200 you'll likely get a 200-franc bill. It's not a problem, you can get change for it anywhere, but it can take people aback.)

No, they use the Swiss Franc.

yes

Switzerland has always used the swill Franc. But Switzerland has always been the centeral of international banking. The shops generally accept all form of currency; and then theres always the old credit card

By the way, they speak 3 different languages. in various areas

Swiss do not spend Euro in their own country.

But almost any larger store accepts Euro - and in touristic places all spendings can be done in Euro.

Of course credit cards are widely accepted as well - and money exchange is possible in almost any village.

Yes they accept the Euro in shops.

As stated above the currency in Switzerland is the Swiss Franc.
A lot of shops especially in the bigger cities also accept Euro bills but mostly give you the change in Francs.
But don't count on it.
