A method for diagnosing an operating state of a switching device including separable contacts, which are driven by an electromagnetic actuator including a coil connected to an electronic control device, and sensors that measure a coil voltage and an intensity of a coil current. The method includes:

Method for diagnosing an operating state of an electrical switching device and electrical switching device for implementing such a method

A switching system for switching an electrical device, comprising: a vacuum interrupter including a fixed electrode, and a mobile electrode, the mobile electrode configured to move between a closed position and an open position. The switching system further comprising an elastic return means configured to apply a driving force to the mobile electrode, and a retaining member for retaining the elastic return means, the retaining member configured to move from a retention configuration, in which the elastic return means is immobilized, into a movement configuration, in which the elastic return means is released. The switching system is configured so that the mobile electrode moves from the closed position to the open position under the action of the elastic return means when the retaining member leaves its retention configuration.
