Disclosed is a method for optimizing a wetting current, for a device for monitoring sensors with contact switches including a current source and at least two switch/resistor assemblies (CT1/R1, CT2/R2) in parallel, including the following steps: the current source (A) supplies the circuit with a nominal current; if a voltage (Vm) measured across the terminals of the switch/resistor assemblies is greater than a threshold voltage (Vs), the threshold voltage being lower than the supply voltage of the current source and than the saturation voltage of the analog-to-digital converter (CAN), then the current source is stopped and a unit for discharging the circuit are implemented; and the current source supplies the circuit again with a supply current (Iwet_c) equal to the nominal current reduced by a predetermined increment. These two last steps are repeated until the measured voltage is lower than the threshold voltage.
