  • the detection elements 27 are connected to an electronic processing unit integrated in the control unit, suitable for determining the absolute angular position of the coupling mechanism 11 from the position and / or movement of the representative piece 25 detected by the detection elements 27.
  • the determination device 24 is for example arranged at the operating button 15. Because the operating button 15 is continuously engaged with the coupling mechanism 11 via the transmission mechanism 17, knowledge of the angular position absolute of the operating button 15 is representative of the absolute angular position of the coupling mechanism 11, the electronic processing unit being capable of such deduction. The fact remains that the determination device 24 could entirely be arranged directly at the coupling mechanism 11, if necessary.
  • the aforementioned representative part 25 may concretely be in the form of a toothed wheel, engaged with a driving wheel 26 belonging to the mechanical transmission elements, this driving wheel being engaged with a toothed crown 28 integral with the operating button 15.
  • the mechanical transmission elements include, in this variant, the transmission mechanism 17.
  • the detection elements 27 comprise for example a magnet 271 secured to the wheel constituting the representative part 25 and a magnetic sensor, for example a magneto-resistive sensor or fixed electronic magnetometer 272 housed in the operating button 15.
  • the reduction ratio between the component part 25 and the operating button 15 is preferably greater than or equal to the number of turns corresponding to the predetermined angular stroke of the rotor of the lock cylinder 101 at which the coupling mechanism 11 is coupled in rotation.
