Two goals in the space of three minutes saw the spoils shared between Switzerland and Norway in Berne.
It took until the 79th minute for Switzerland, who started as Group E leaders, to break the deadlock through Mario Gavranovic.
But Norway, looking to recover from an opening loss to Iceland, were level moments later when Brede Hangeland headed in from a corner.
The only surprise was that there were not more goals in a match that produced endless chances for both teams - and saw three efforts hit posts.
Norway were the first to hit the frame of the goal when John Arne Riise's free kick found his Fulham team-mate Hangeland in the 16th minute, but his header struck the upright.
Ten minutes later, Switzerland's Tranquillo Barnetto was likewise denied by a post when he tried a header from the left side of the area.
A string of chances came and went before the deadlock was finally broken with 11 minutes left.
Xherdan Shaqiri swung in a corner to find Granit Xhaka, and he headed the ball back across goal for Gavranovic to finish from close range.
But moments later Hangeland cut short the home fans' celebrations, again getting on the end of a cross from Riise, this time a corner, to head into the top right-hand corner of the goal.
There was still time for late drama, with Norway denied when Tarik Elyounoussi's 90th-minute shot from 25 yards struck a post before Daniel Braaten fired wide seconds later.
