Rotary switch assembly, in particular of a steering wheel column integrated module of an automotive vehicle

A rotary switch assembly (1), in particular of a steering wheel column integrated module of an automotive vehicle, comprising a support member (2), a control ring (4) held rotationally by said support member (2), a slider (5) disposed slidably along an axis (A) of rotation of said control ring (4) and cooperating with an activating member (3) to generate electrical signals, wherein an angular displacement of said control ring (4) is converted into an axial displacement of said slider (5),

• wherein
• said slider (5) is provided with means (51, 25) for restoring a slider (5) equilibrium position along said axis of rotation (A),
• said control ring (4) is provided with a number of substantially equiangularly disposed radial protrusions (42a, 42b),
• said slider (5) is provided with a radial protrusion (52a, 52b) that:
• extends in an area of a circumference defined by said radial protrusions (42a, 42b) of said control ring (4),
• remains between two adjoining radial protrusions (42a, 42b) of said control ring (4) when said slider (5) is in the equilibrium position, and
• cooperates with said radial protrusions (42a, 42b) of said control ring (4), and
• wherein
• said radial protrusion (52a) of said slider (5) or said radial protrusions (42b) of said control ring (4) has/have a form of a cam (8) having two angularly external surfaces (81, 82) slanted at a same orientation (α1, α2) with respect to said axis of rotation (A) such that an angular displacement of said control ring (4) is converted into an axial displacement of said slider (5).
