Abstract

A multifunctional rotary switch for operating an electronic device is providing having a roller with an axis of rotation. The roller has a bidirectional rotational mode of operation where the roller rotates in both a clockwise and counter clockwise direction around the axis, a translational mode of operation where the roller is moved in a direction substantially parallel to the axis of rotation and a pushing mode of operation where the roller is moved in a direction substantially perpendicular to the axis of rotation.

Claims

1. A multifunctional rotary switch for operating an electronic device, the rotary switch comprising a roller with an axis of rotation, the roller having a bidirectional rotational mode of operation around the axis, and having a translational mode of operation, where the translation takes place substantially parallel to the axis of rotation, the roller further having a pushing mode of operation where the roller is moved in a direction substantially perpendicular to the axis of rotation.

2. The multifunctional rotary switch of claim 1, where the roller has a cylindrical shape, and that the axis of rotation is the symmetry axis of the cylinder.

3. The multifunctional rotary switch of claim 1, where the roller has the shape of a spindle with cut off tips, and that the axis of rotation is the symmetry axis of the spindle.

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.

16. The multifunctional rotary switch of claim 14, where a function in the menu is selected by operating the rotational mode of operation.

24. The multifunctional rotary switch of claim 23, where the mechanism is arranged substantially inside the roller.

25. The multifunctional rotary switch of claim 1, further comprising an arrest mechanism for arresting the rotation of the roller around the axis in the rotational mode of operation at a predetermined angle.

26. An electronic device comprising at least a first and second multifunctional rotary switches, where both the first and second rotary switches including a roller with an axis of rotation, the roller further having a bidirectional rotational mode of operation around the axis, a translational mode of operation parallel to the axis and a pushing mode of operation perpendicular to the axis, where at least some functions of the electronic device operated by the first multifunctional rotary switch differ from functions of the electronic device operated by the second multifunctional rotary switch.
