Claim Text:
1. A switching device, comprising: at least one pair of fixed contacts and, for the or each pair of fixed contacts, a movable contact that is movable between a closed position and an open position, the fixed contacts being, in the closed position the movable contact, electrically connected to one another via the movable contact and being electrically isolated from one another in the open position of the movable contact, a contact holder capable of holding in place the or each movable contact, the contact holder being movable, along a vertical direction, between a first position corresponding to the closed position of the or each movable contact and a second position corresponding to the open position of the or each movable contact, and an actuator capable of actuating a translational movement of the contact holder between its first and second positions, wherein the switching device includes: a plate capable of applying a force on the movable contact holder, the actuator being capable of actuating the translational movement of the contact holder between its first and second positions via the actuation of the movement of the plate, the plate being movable relative to the movable contact holder, a sensor capable of measuring the movement of the movable plate along the vertical direction relative to the movable contact holder, during the actuation of the movement of the plate in order to drive the translational movement of the contact holder from its first position to its second position, and a detection member for detecting a fault or malfunction in the switching device based on at least one value measured by the sensor.
