Supply for an electronic circuit controlling electrical devices, with an electric current source, a controlled switch, inserted between the electric current source and the electronic circuit, and an electrical control signal source, which throw the controlled switch into its conducting state. To improve the utilisation of the supply in electronic circuits, a delay element Z, inserted between the controlled switch S and the source of electrical signals, keeps the controlled switch in the conducting state for a predetermined period, as a function of the control signals. <IMAGE>
