<p>The present invention relates to a circuit for overvoltage protection of a component (L) having a resistor of value R connected to a supply line of given polarity, comprising a detector of overvoltage at the terminals of the line (1), a first normally-closed switch (S1) in series on a conductor of the line and thrown open by the detector, and a second switch (S3) in series with a resistor of like value R, arranged between the conductors of the line and thrown by the detector in a manner complementary to the first switch. <IMAGE></p> |
