Zusammenfassung:	The switch (10) has a manipulation lever (12) integrated to a plate (14) with a locking finger i.e. effort finger (30), elastically stressed against an effort cam (32) with a preset profile. The profile has an indexing notch (40) in a stable neutral position, and is chosen to produce a secondary effort curve that is added to a primary effort curve for producing a main effort curve representing sum of the primary and secondary curves. A profile of the main curve is equal to that of the primary curve, and height of the main curve is greater in absolute value than that of the primary curve. Le commutateur (10) selon l'invention comporte un levier (12) de manipulation solidaire d'une platine (14) qui pivote autour d'un axe transversal (A1), par rapport à une embase, entre une position neutre et une position actionnée. La platine (14) comprend un premier et un second doigts d'encliquetage (18, 30) sollicités élastiquement contre une came de sensation (20) et contre une came d'effort (32). Le profil de la came d'effort (32) est adapté pour produire une courbe d'effort secondaire.
