Abstract:
An electrical circuit for transmitting the state of one of a parameter and of a piece of equipment and operative to be connected to terminals of a power supply battery, the circuit comprising:an isolated link between said electrical circuit and an output for sending an item of state information; and a state switch whose open or closed position is representative of the state information and determines, while not testing, whether or not a current flows in said electrical circuit; the electrical circuit transmitting state information from the state switch to the output via the isolated link; the electrical circuit comprising means for regulating the magnitude of the current flowing through the state switch, said means for regulating comprising switch means, connections between component elements of the electrical circuit and comprising inductive energy storage means in series with the state switch and capacitive energy storage means which, under steady conditions, alternate between constituting means for storing and means for restoring a fraction of the energy of said electrical circuit, depending on the alternating state of said connections between the component elements of the electrical circuit, as determined by the switch means.
