Shift register circuits in which each register stage comprises a magnetic lutch relay and a capacitor adapted to be coupled to a movable contact of said relay through a double-throw transfer switch, two stationary contacts of said relay being connected respectively to a reference potential and a first power source of a first potential, coil of said relay having one end connected to a second power source of a second potential lower than said first potential and the other end adapted to be coupled to the capacitor in the immediately preceding stage through the double-throw transfer switch in the immediately preceding stage.
