Britton was shown a red card for thrusting an arm into the face of Kevin Muscat when the game was finely balanced at 1-1.
Ronald de Boer then provided a winning goal that extended Rangers' lead at the top to four points on a day when it had, for a long time, appeared possible even likely that Alex Burns' early opener for Thistle might turn out to be the winner.
