The lethality test system (LTS) is an experiment which will utilize a light-gas gun-railgun combination to accelerate projectiles for impact studies. The authors describe the design and testing of the switching devices which will be required to produce energy transfer and compression in the LTS. Switches on the primary side of the transformers include three arrays of three series by two parallel vacuum interrupters. Also on the primary are specially designed mechanical dump switches capable of 100 kV open-state stand-off and 50 kA conduction with a total action of 2*1010 A2s. The third type of primary switch is an explosively actuated, 100 kV, isolation switch. A fourth type of switch is used both to initiate generator discharge and to crowbar the primary winding of each transformer. Switches on the secondary side of the transformers include three explosively actuated make-before-break switches. Also on the secondary are seven high-current mechanical make switches. Four of the seven switches are used as secondary dump switches and must conduct 500 kA with an action of 5*1010 A2s.
