The Scottish quartet were in command throughout against the Germans, leading 5–2 at the break before clearly increasing momentum, but the hitherto undefeated Swiss proved to be tougher opposition.
Mouat’s team led 3–2 at the break – a steal in the third proved the difference – and it took until the seventh end for either side to register more than one score.
It was the Swiss who took a 4-3 lead, but it all came down to the end.
Britain needed one to tie and two to win. They had to settle for the first one, which means an extra ending. However, Switzerland maintained a strong lead and secured a convincing victory.
“Another day we will come away with a win,” Moat told BBC Sport.
“They will be tough to beat, but we know we are playing very well, and it will be exciting to play them again.”
Earlier in the day, Britain’s women were unable to repeat their win over Canada against the Swedish rink that had denied them European gold in November.
Undefeated Sweden led 7-3 at the break – after scoring three with the hammer twice – and stole one in the sixth to put the game away.
Rebecca Morrison’s rink kept fighting but ultimately lost 10–7, leaving their semi-final hopes in limbo.
Any hopes of reaching the knockouts will need at least four wins in their last five round-robin matches, starting against Denmark on Monday (08:05 GMT).
“It’s really difficult at this stage – it’s almost a miss, and we’re centimetres away from having a great shot,” Morrison told BBC Sport.
“It’s disappointing, but that’s what happens at the Olympics.”
We failed to reach our peak performance.
The women are back on the ice on Monday against Denmark (08:05 GMT) and Switzerland (18:05), while the men face Norway (13:05).
