Abstract :
PUSH-BUTTON SWITCHING is a continuation of the development of reperforator switching in the handling of telegrams through central telegraph offices. It is essentially a mechanization project in which the human element is largely replaced with mechanical and electric devices. The desired goal was faster and more accurate transmission of telegrams at lower operating costs. All of these goals were achieved in large measure with the successful development and application of reperforator switching.
