| 摘要 |
An ultra-fast-acting pyrotechnic changeover switch, usable especially in connection with high-energy pulse sources, comprises a fixed annular electrode (28), an axial electrode (26) and a pyrotechnic charge placed in a cavity (29) with a thin wall (30) of the axial electrode, situated in line with the solid electrode. Firing of the charge sticks the thin wall against the fixed electrode and welds it to this electrode. <IMAGE>
