ABSTRACT:
Electronic switch for low-voltage supply circuits completed with CMOS technology and comprising a first, a second and a third circuit element (SW1 ,SW2,SW3) consisting each of a pair of complementary transistors. The first and second of said elements (SW1,SW2) are inserted between two connection terminals of the switch (A,B) while the third element SW3 is inserted between a node (C) included between the first and the second element of a voltage reference (VCM). The first and second element are driven to conduction in phases (.phi.1) not overlapping the phases (.phi.2) in which it conducts the third element.
