Claim 5:
6. The method according to claim 4, wherein a coil current spike is applied using the electronic control device during a test phase included in a holding phase of the switching apparatus, during which the coil current has a holding current value that is strictly greater than a stall value of the coil current, below which the electromagnetic actuator is not kept energized in the closed position, with the trend of the coil current having an increasing portion, during which the measurements of the coil current are taken that are used for computing the second value of the magnetic flux, and a decreasing portion, during which the measurements of the coil current are taken that are used for computing the first value of the magnetic flux.
