Having already been defeated by Korea and the USA, European champions Scotland needed a win against Switzerland to keep their hopes of reaching the knockout stages of the tournament alive.
But instead defeat leaves them second from bottom in the 12-team table.
“When you’re throwing the rock well like that and you don’t get the results, there’s nothing you can do,” said Scotland skip Eve Muirhead.
“We were shooting well out there and it came down to one or two misjudgements.”
Scotland could still mathematically reach the play-offs, one of seven teams in the tournament to only record two wins so far, albeit with the Czech Republic and Italy having played one less match than every other team.
Mirjam Ott’s Switzerland sit in fourth with four victory’s to their name, level with South Korea and Sweden.
Heather Nedohin led her Canadian team to a 7-5 victory over Russia, despite the loss of regular second Jessica Mair.
