Delayed switching through a D.C. voltage - has electronic switch flip-flop with two differential inputs and two RC circuits

摘要

The electronic swtich, e.g. a thristor, is controlled by the flip flop. the R.C. junction points of the R.C. circuits are connected to the flip flop differential inputs. Stationary capacitor voltage and time constant of the first R.C. circuit are smaller than those of the second R.C. circuit. If the flip flop has one transistor, the differential inputs are connected to the transistor base and emitters. If the flip flop has two transistors, the second transistor base is connected to the first transistor collector, and its collector to the first transistor base.
