In a control device for two switching transistors (7, 13) in a direct-voltage measuring circuit, which are alternately switched on and off by pulsating control signals (E, F) carrying the same amplitude, in which the switch-off edges of the control signals (E, F) have a variation approximating the edge of a trapezoid, it is ensured, in order to retain the shortest possible switch-over time of the switching transistors with the least possible falsification of the measurement, that each switch-on edge from the beginning of a switch-over time to the end of the switch-off edge occurring within this switch-over time, has a much lesser steepness than the switch-off edges and in the subsequent section a straight-line, a much steeper variation than the switch-off edges. <IMAGE>
