Jane Ross scored twice and earned her side a penalty as Scotland's women routed their Swiss counterparts at the Falkirk Stadium.
Ross headed the home side into the lead after 14 minutes and Jule Fleeting soon nodded the second.
A low shot from a tight angle by Ross and Kim Little's converted penalty on the half-hour established a 4-0 half-time advantage.
Jennifer Beattie slotted home the fifth 18 minutes from the end.
The Scots are next in action on Tuesday against Belgium at the same venue.
