Claim 0:
1. A switch system comprising:
a power line for supplying a charge from a voltage source, said power line comprising:
a main switch comprising a first main terminal and a second main terminal, between which a main current is intended to pass, and
a control terminal for selectively placing the main switch in a closed, open or semi-closed state, the main switch in the semi-closed state being equivalent to a variable resistor controlled by the control terminal and connected between the first and the second main terminal; and

a current-limiting device configured to, when the main current exceeds a maximum current threshold, decrease a control current entering the control terminal, so as to cause the main switch to transition from the closed state to the semi-closed state, so as to limit the main current,
wherein the power line further comprises a measurement resistor, through which the main current passes, and
wherein the current-limiting device comprises a first and a second terminal, said measurement resistor being connected between the first and the second terminal, and the current-limiting device is configured to vary the reduction in the control current as a function of a resistance voltage between the first and the second terminal, in order to place the main switch in the semi-closed position when the resistance voltage exceeds a threshold voltage.
