4. The multifunctional rotary switch of claim 1 , where the roller has projections on its circumferential face where by the switch can be easily operated by hand without slipping.
5. The multifunctional rotary switch of claim 1 , where the roller further includes covers at both end faces that are perpendicular to the axis of rotation.
6. The multifunctional rotary switch of claim 4 , where the covers have a semi-spheroidal shape.
7. The multifunctional rotary switch of claim 1 , where the roller is mounted in such a way that the axis of rotation of the roller is substantially parallel to the surface of a component on which the roller is mounted.
8. The multifunctional rotary switch of claim 1 , where the multifunctional rotary switch is mounted on a front surface inside a vehicle.
9. The multifunctional rotary switch of claim 1 , further including electrical switches arranged outside the roller in proximity of each of the ends of the roller along the axis of rotation, the electrical switches being actuated by an end of the roller when the roller is operated in the translational mode of operation.
10. The multifunctional rotary switch of claim 1 , where the roller further includes a switching lever arranged inside the roller and electrical switches arranged inside the roller on both sides of a switching lever, where the switching lever is moved together with the roller when the roller is operated in the translational mode of operation and where one of the electrical switches is switched by the switching lever depending on the direction of translational operation.
11. The multifunctional rotary switch of claim 1 , characterized in that operating any of the modes of operation selects and executes a function of the electronic device.
12. The multifunctional rotary switch of claim 1 , where the translational mode of operation is bidirectional and operates one function for each direction of operation.
13. The multifunctional rotary switch of claim 1 , where the translational mode of operation is bidirectional and operates the same function for both directions of operation.
14. The multifunctional rotary switch of claim 1 , where operating the translational mode of operation brings up a menu on a display that is part of the electronic device.
15. The multifunctional rotary switch of claim 1 , where the pushing mode of operation brings up a menu on a display that is part of the electronic device.
