"I wasn't that nervous, but I knew it was an important moment," Bachmann told reporters.
Ana-Maria Crnogorcevic, Switzerland's top scorer and most capped player, fired over from close range before Bachmann's penalty put them ahead.
"To come to this level and play against players from Europe, against a team like that is miraculous."
Switzerland top Group A on goal difference ahead of co-hosts New Zealand, who upset Norway 1-0 on Thursday.
