PCT No. PCT/FR85/00115 Sec. 371 Date Jan. 16, 1986 Sec. 102(e) Date Jan. 16, 1986 PCT Filed May 13, 1985 PCT Pub. No. WO85/05512 PCT Pub. Date Dec. 5, 1985.The invention concerns a drive interface (1) for an electronic static switch (3) such as a blocking thyristor or a transistorized blocking switch; this interface is inserted between said static switch and a control stage (2) designed to generate a logic control signal. Said interface comprises a circuit (5) for detecting the voltage across the two power electrodes of the static switch (3) and a drive circuit (6) receiving the signal emitted from the circuit (5) and the control signal; this drive circuit is designed to assure a polarity on the control electrode (3c) of the static switch such that: said polarity corresponds to blocking the switch when the control signal carries an OFF command, and/or the voltage across the power electrodes is different from 0, said polarity corresponds to the conduction state of the switch when the control signal corresponds to permission to conduct an the voltage across the power electrodes is near 0.
