The arrangement ofthe high-tension switch in relation to the mercury break is shown inFig. 193, the respective parts by similar letters on the three P are the contacts through which the primary current passes tothe coil when they are connected together by the revolving mercury S are the high-tension contacts connected in series with the X-ray tubecircuit, the conductor C being so set, in relation to the interrupter, that thewhole of the high-tension current passes through it, which is produced by the.
