Definitions

• the present invention relates to a control device such as a thumbwheel switch.
• An object of the invention is to design a control device capable of tilting on an axis with a return to the center without residual mechanical play.
• the invention proposes a control device comprising: - a body comprising a printed circuit, an actuator movable in pivoting relative to the body around an axis of rotation, a torsion spring comprising two end strands in bearing on two respective bearing surfaces of the actuator, said torsion spring being arranged to bias the actuator in rotation towards a rest position, at least one magnet rigidly secured to the actuator, and a magnetic field sensor arranged on the printed circuit opposite the magnet adapted to detect the angular position of the magnet and to produce an electric signal as a function of said detected angular position, characterized in that it comprises two stops rigidly fixed to the body, an element respective elastic being arranged between each abutment and the body, each abutment comprising a bearing surface on a respective end strand of said torsion spring.
• the second stops limiting the rotation around the axis are, at the end of their travel, in contact with the contact surfaces arranged in the body.
• Figures 3A and 3B are sectional views of a control device according to the invention.
• Figure 4 is an exploded view of a control device according to the invention.
• rotor 13 of actuator 1 comprising magnet 6 and torsion spring 7 is inserted into body 20, aligning bore 55 with orifices 51. ends of the strands 71 of the torsion spring 7 bear against the first stops 8, by compressing the respective elastic elements 9 arranged on the axes 84 of said stops 8. The first stops 8 slide in the orifices 86 in the bottom 22. The force compression of the elastic elements 9 being less than the compression force of the torsion spring 7, the torsion spring 7 does not undergo deformation during this step.
