Transistor switching circuits with shortened response times
 The response time of an ordinary or differential transistor switching circuit controlled by the charging of a capacitor C.sub.1 is shortened by rapidly charging the capacitor through a transistor Q.sub.6 connected in parallel with the charging resistor R.sub.1 of the capacitor. The transistor is rendered conductive before the differential switching region is reached in response to the capacitor charge reaching a predetermined level, whereby the charging curve thereafter follows a steep rise to sharply reduce the switching time.
