A high-voltage switch (24) has a high-voltage input terminal (29), receiving a high voltage (HV), and an output terminal (31). A pass transistor (36), having a control terminal, is connected between the high-voltage input terminal (29) and the output terminal (31). The output of a voltage-multiplying circuit (40) of the charge-pump type is connected to the control terminal. The voltage-multiplying circuit (40) is of a symmetrical type, has first and second charge-storage means (41, 42), receiving a clock signal (CK) of a periodic type, and has a first circuit branch (44, 48) and a second circuit branch (45, 49), which are symmetrical to one another and operate in phase opposition with respect to the clock signal (CK).
