The invention relates to a switch system () comprising a power line () for supplying a charge from a voltage source (+Vbat), said power line having a main switch (Q) comprising a first main terminal (D) and a second main terminal (S), between which a main current (Ip) is intended to pass, and a control terminal (G) for selectively placing the main switch (Q) in a closed, open or semi-closed state, the main switch (Q) in its semi-closed state being equivalent to a variable resistor controlled by the control terminal and connected between the first and the second main terminal, characterized in that the switch system () further comprises a current-limiting device () designed to, when the main current (Ip) exceeds a maximum current threshold, decrease a control current (Ig) entering the control terminal (G), so as to cause the main switch (Q) to transition from the closed state to the semi-closed state, so as to limit the main current.
