An electrical storage element comprises two controllable elements, such as field effect transistors, controllable into conducting or cut off positions in phase opposition and in dependence on the state of charge of storage capacitances, one positioned in parallel with the control path of each controllable element, charging and discharging circuits for each storage capacitance, these circuits having separate inputs to which clock pulses are applied cyclically so as to charge both capacitances and then discharging one of the capacitances depending on its original state of charge.
