Abstract

A switch arrangement for switching a principal function and for switching at least one secondary function by which at least one secondary function is switchable whenever the principal function is turned on. The control or controls for switching the at least one secondary function is covered by a cover whenever the principal function is not activated, and the cover of the control or controls for the at least one secondary function is moved such that the control or controls become visible and accessible when the principal function is activated.

Claims

1. A switch arrangement for switching a principal function and at least one secondary function such that the at least one secondary function is activateable whenever the principal function is activated, comprising:

a cover; and

at least one control for operating the at least one secondary function;

wherein;

the control for operating the at least one secondary function is covered when the principal function is deactivated; and

to permit activation of the at least one secondary function, the cover must be moved such that the at least one control is visible and accessible when the principal function is activated.

2. The switch arrangement according to claim 1, wherein the cover is mechanically coupled to a control piece for activating the principal function.

3. The switch arrangement according to claim 2, wherein the cover comprises the control piece, forming a handle for activating the principal function.

4. The switch arrangement according to claim 2, wherein the control piece for activating the principal function is a slide switch.

5. The switch arrangement according to claim 3, wherein the control piece for activating the principal function is a slide switch.

6. The switch arrangement according to claim 2, wherein the control piece for activating the principal function is a rotary switch.

7. The switch arrangement according to claim 2, wherein the control piece for activating the principal function is a rotary switch.

8. The switch arrangement according to claim 5, wherein the cover covers sectors of a circle along an axis of rotation of the rotary switch, and rotates with the rotary switch when the rotary switch is operated.

9. The switch arrangement according to claim 1, wherein the at least one control is one of a pushbutton switch, a toggle switch and a momentary contact switch for switching the at least one secondary function.

10. The switch arrangement according to claim 1, wherein via the control piece for activating the principal function, different principal functions can be switched, based on the position of the control piece, and the cover is moved in unison with the control piece such that the at least one control for operating the at least one switchable secondary function becomes visible, accessible and switchable based on the activated principal function.

11. The switch arrangement according to claim 1, wherein upon the movement of the control piece for activating the principal function to an "OFF" position, the at least one control is covered by the cover, and the principal function and corresponding secondary functions of the at least one control are deactivated.

12. The switch arrangement according to claim 1, wherein the switch arrangement is in a motor vehicle.

13. A switch arrangement for switching a principal function and at least one secondary function in an automobile, comprising:

a control piece for controlling the principal function;

a cover coupled to the control piece; and

a control piece for controlling the at least one secondary function;

wherein the control piece for controlling the at least one secondary function is covered when the principal function is deactivated, and to permit activation of the at least one secondary function, the cover moves such that the at least one control is visible and accessible when the principal function is activated.

14. A switch arrangement for switching a principal function and at least one secondary function in an automobile, comprising:

a first switch element for controlling an operating mode of said principal function; and

a second switch element for controlling an operating mode of said at least one secondary function;

wherein said first switch element is movable between a first switching position in which the principal function is in a first operational mode and said second switch element is inaccessible, and at least a second switching position in which said principal function is in a second operating mode and said second switch element is accessible to control an operating mode of said secondary function.

15. The switch arrangement according to claim 14, wherein said principal function is deactivated in said first operating mode and is activated in said second operating mode.

16. The switch arrangement according to claim 14, wherein said first switch element includes a member which covers said second switch element when said first switch element is in said first switching position and which exposes said second switch element when said first switch element is in said second switching position.

17. The switch arrangement according to claim 15, wherein said first switch element includes a member which covers said second switch element when said first switch element is in said first switching position and which exposes said second switch element when said first switch element is in said second switching position.
