ABSTRACT:
An electrical switch includes an alternating series of first and second switch cells. Each first cell includes a first conductive member with a first bore and a first insulative member conformally located in the first bore and movable through the first bore. Each second cell includes a second insulative member with a second bore and a second conductive member conformally located in the second bore and movable through the second bore. The first and second bores have substantially the same cross-section. The cells are mounted end-to-end in the alternating series so that the bores align. Severable diaphragms electrically interconnect the second conductive member of each second cell to the first conductive member of the first cells adjacent to the second cell. The first insulative members and the second conductive members are simultaneously moved to simultaneously sever the diaphragms. A plurality of insulated gaps are thereby produced between the first and second conductive members of adjacent cells. Additional insulated gaps are produced by covering the first bore of the first conductive member and the second conductive member with insulative layers.
