The title app. was composed of a D.C to A.C convertor, a trans., a main discharge capacitor(3), a flash discharge tube(9) and a trigger cct.. As S.W(2) was electrically coupled to the trigger cct. and mechanically coupled with S.W(1), even though the trigger S.W(4) was closed when S.W(2) was open, the charge in the condenser (6) didn't discharge to the trigger coil(10) thus preventing a fault oper. due to the residual charge in the condenser(3).
