A switching device, including:



a main switch configured to be displaced between a closed position of a main circuit and an open position,
a vacuum interrupter including:

a fixed electrode,
a mobile electrode, configured to be displaced between:

a first, so-called closed, position, and
a second, so-called open, position, in which the electrodes are apart,




a palette configured to make the mobile electrode switch over from the first position to the second position and comprising an electrically conductive plate, the main switch being configured to drive the palette via the plate,
a connection wire electrically linking the plate and the mobile electrode, the wire being in electrical contact with a tube disposed in an accommodating recess of the plate,

wherein the accommodating recess comprises a wall exerting an elastic holding force on the tube.
