Abstract
A two pole electrical switch has side-by-side movable contacts operated by a single rocker/actuator of the type having side-by-side pin recesses. Two pins in these recesses are spring biased toward the movable contacts to achieve contact closing, but one pin has its end offset from the other pin end so the closing is sequential rather than simultaneous.
