  • Spark switch having coaxial electrodes with increased electrode surface area exposure
    Patent number: 6037715
    Abstract: A geometry for a spark switch includes an inner electrode surrounded by an outer electrode. The placement of the inner electrode within the outer electrode substantially increases the exposed overlapping surface area of the electrodes. The increase in surface area of the electrodes results in a proportional increase in the operational life of the switch. The design of the spark switch also causes the outer electrode to shield a surrounding insulation layer against debris that would otherwise contaminate an insulation layer.
