  • Patent number: 4481630
    Abstract: A spark gap switch is disclosed. The spark gap comprises opposite and adjacent electrodes and a trigger arrangement for triggering a discharge arc between the opposite and adjacent electrodes. The trigger arrangement includes a solid insulative material to facilitate a discharge between trigger electrodes to trigger the spark gap. The trigger arrangement is located rearwardly of the adjacent electrode to position the solid insulative material in a manner to prevent a main discharge arc affecting the structural integrity of the solid insulative material. Such an arrangement provides protection for the solid insulative material to increase lifetime of the unit and has the capability of reducing jitter.
