A circuit for the preferential starting of a stage of an electronic sequence having a holding circuit has two supply voltage sources of different potentials for driving the circuit, the voltage necessary for starting the preferred stage dropping across a component connected between a control electrode of a switching transistor setting the stage in operation and the potential connection common to the circuit, this component being connected in series with a voltage divider and a constant voltage element at the higher value voltage source, the tapping of the voltage divider being connected by a unidirectional component to the voltage source of lower potential and the loading of this voltage source, resulting only with the presence of the higher potential, being eliminated or considerably reduced when using the voltage of lower potential.
