A low-level electronic subcommutator

A Low-Level Electronic Subcommutator has been designed and developed by Radiation, Inc. This subcommutator (or commutator) uses the low-level switch described
¹
at the 1957 IRE National Convention and was a parallel development with the switch. Semiconductor devices were used extensively throughout the subcommutator, thus permitting miniaturization and ruggedization even though the circuits are extensive and complex. This paper explains the functioning of this subcommutator by describing the system for which it was designed, the circuits within the subcommutator, and its potential applications.
