Before revision:  Orientational control causes the switch to deviate from Poissonian behaviour: the distribution of times in the on state shows a peak and successive flip times are correlated . This model should provide a framework for understanding how DNA inversion switch architecture determines switch flipping statistics, with relevance to the role of such switches in microbial population dynamics .
