Switching device for an electrical apparatus

A switching device for an electrical apparatus, the switching device comprising:

• a vacuum interrupter comprising a first electrode and a second electrode which can be displaced displaceable between a closing position and an opening position;
• a drive element mechanically connected to the second electrode;
• a movable element displaceable between a first position permitting passage of electrical current in a main electrical circuit of the electrical apparatus, and a second position which prevents the passage of electrical current in the main electrical circuit,
• the movable element comprising:
• an electrically conducting blade;
• a support secured to the electrically conducting blade,
• wherein said movable element is configured to:
• according to a first direction of displacement corresponding to passage from the first position to the second position, drive the drive element of the movable electrode via the conducting blade;
• and
• according to a second direction of displacement, opposite the first direction of displacement, and corresponding to passage from the second position to the first position, drive the drive element of the movable electrode via the support,
• wherein the support comprises a drive surface configured to be in contact with a receiving surface of the drive element during passage of the movable element from the second position to the first position,
• and wherein:
• the drive surface of the support has a curved shape;
• and
• the receiving surface of the drive element has a curved shape.
