Switching system of an electrical device

A switching system for comprising:

• a vacuum breaker comprising:
• a fixed electrode, and
• a mobile electrode, configured to move between a closed position in which the fixed electrode and the mobile electrode are in contact with each other so as to allow electrical current to pass, and an open position in which the fixed electrode and the mobile electrode are separated from each other so as to prevent electrical current from passing;
• a driving plate connected to the mobile electrode for driving the mobile electrode;
• a main switch to move between a first position allowing electrical current to pass in a main electric circuit of the electrical device and a second position preventing electrical current from passing in the main electric circuit, the main switch being configured to drive the driving plate during a transition from the first position to the second position, so as to cause the mobile electrode to make the transition from the closed position to the open position;
• and
• a contact-maintaining element configured to maintain mechanical and electrical contact between the driving plate and the main switch and limit acceleration of the driving plate while the driving plate is being driven by the main switch.
