CONTROL MODULE COMPRISING A TOUCH-SENSITIVE SURFACE

摘要

The invention relates to a control module (10) comprising a stationary control member (20, 22) provided with a touch-sensitive surface (24) such as to provide a control signal representative of the position or movement of a finger on the sensitive surface (24). The module is characterised in that the sensitive surface (24) of the control member (20, 22) comprises a generally donut-shaped portion about a main axis (A1) and in that the control module (10) comprises a control unit (28) for detecting the so-called axial component (Ca) and the so-called circumferential component (Cc) of a touch movement on the sensitive surface (24) such as to produce a control signal established according to said two components (Ca, Cc).
