The invention proposes a switch comprising an actuation member in the form of a pushbutton (18) comprising an actuating portion (28) being arranged, when an external force is applied to the pushbutton (18), to be moved vertically relative to the housing between a pushbutton upper position and a pushbutton lower position, said pushbutton (18) and a tilting driving member (84) forming a movable mechanical assembly, characterized in that it comprises electrical switching means (100, 200) for generating signals representative of changes of position of the one (18) and/or of the other (84) of the two components of the movable assembly, said electrical switching means including a sensing switch (100) for sensing the changes of position of the pushbutton (18) between its upper position and its lower position, and a detecting switch (200) for detecting the changes of position of the tilting driving member (84) between its upper position and its lower position.
