A high voltage electrical switching apparatus including a base formed from a pair of flat dielectric plates supported in a spaced relation, a number of elongate elliptically shaped contacts positioned between the plates at equally spaced intervals, a dielectric bar mounted for linear motion between the plates, a pair of electrically conductive plates mounted on opposite sides of the bar, each conductive plate including a pair of louvered contacts spaced a distance apart sufficient to electrically interconnect two of the elongate contacts, and a Geneva drive assembly for moving the bar in steps of equal distance.
