Paul Clement departed Swansea as head coach last night and Britton agreed to take temporary charge.
He became player-coach at the club only last month but is confident of having a short-term impact and lifting the side off the bottom of the division.
"That’s one of the reasons I agreed to take this role – because I believe I can have an effect on the team in the immediate future,” the club veteran told Swansea's official website.
"I am sure the fans will be behind the team on Saturday and hopefully I can help lift the players. We have to make sure we’re in the right frame of mind and hopefully that will lead to a result."
Britton will be assisted by Swansea's Premier League 2 coaches, Gary Richards and Cameron Toshack.
