Classification: CPC H | IPC H

Claim 0:
1. A switching system for switching an electrical device, comprising:
a vacuum interrupter comprising:
a fixed electrode,
a mobile electrode, configured to move between:
a first position, known as the closed position, in which the fixed electrode and the mobile electrode are in contact with one another so as to allow electrical current to pass, and
a second position, known as the open position, in which the fixed electrode and the mobile electrode are separated from one another so as to prevent electrical current from passing,

an elastic return means configured to apply a driving force to the mobile electrode,
a retaining member for maintaining the position of the elastic return means, the retaining member being configured to move:
from a first configuration, known as the retention configuration, in which the elastic return means is immobilized, into
a second configuration, known as the movement configuration, in which the elastic return means is released,, the switching system being 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, the switching system comprising a main switch of the electrical device, wherein the main switch is able to move between a first position allowing electrical current to pass in a main electric circuit and a second position preventing electrical current from passing in the main electric circuit, and wherein the main switch is configured so that the retaining member leaves its retention configuration when the main switch moves from the first position allowing electrical current to pass to the second position preventing electrical current from passing, and wherein the retaining member is configured to move from the retention configuration to the movement configuration under the action of a magnetic component connected to the main switch.
