    Abstract: An isolating switch having spherical, ellipsoid, toroid or spheroid electrodes and a retractable switchblade. The electrodes in the open gap position have a relatively high withstand on switching voltage surge, impulse voltage and with a relatively small gap space. The extension of the retractable switchblade to contact both electrodes corresponds to the closed position of the switch while retraction of the switchblade into one of the electrodes corresponds to the open position. In that latter position, an open gap is produced between the electrodes and results in a substantially uniform electrostatic field in the gap. This has the advantage that the switch open gap may be made substantially shorter than the distance from the electrodes to ground and yet insure that any flashover will be between the electrodes and ground rather than across the switch open gap.
