Multi gap spark switches

Most people dealing with pulsed power at some moment of their activity were dealing with spark switches. In Russia, there do not exist switches produced by industry. The author's Russian colleagues believe that the spark switch is a very simple device and produce switches themselves when necessary; a practice that foreign colleagues are doing the same when the switches produced by industry do not satisfy some given requirements. There exist a lot of different switch designs, trigger schemes and so on. In the paper the author discusses the switches that have been produced in previous years and also about the switches now being produced.
