    As a start point for our development in MV closing switches the Sandia Rimfire switch was chosen that was successfully proved in different installations during the long period of time. This gas switch consists of a stack of intermediate electrodes, that form a self breakdown section, connected in series with a trigger gap. The voltage across the self breakdown section relates to that of the trigger gap as approximately 3:1. The switch is triggered by closing the trigger gap resulting in overvoltage in the self breakdown section. After the gas gaps in this section break down the whole discharge current flows in multiple channels in self breakdown section and through the single spark in the trigger gap. Unlike in Rimfire, the discharge current in our switch flows in multiple channels along the whole length of the switch. That is because in our switch same electrodes as in self breakdown (or top) section are installed in parallel to the trigger gap, and also because the trigger gap is connected in series with an inductance which limits the discharge current through this gap. Therefore, after the trigger gap is closed the charge voltage is applied to the gaps in the top section of the switch, and after they break down - to the gaps in the bottom (trigger) section. If the current limiting inductance is large enough, the bottom gaps break down and the current flows in multiple channels along the whole switch. In report we present the design of several switch modifications and the results of the experiments on a testbed with 2.3 MV output voltage. On the given step of the work the main goal was to prove the multi channel discharge along the whole length of the switch. The problems related to the switch body flashover were also considered but they will be the main goal of our future work in this field.
