Abstract

The present invention relates to a switching element ( 10 ) for a control device, in particular of a domestic appliance. The switching element ( 10 ) comprises a rotatable and shiftable rim element ( 14 ) being rotatable around and shiftable along the same axis. The switching element ( 10 ) comprises a stator element ( 20 ). The rim element ( 14 ) is rotatably and shiftably coupled to the stator element ( 20 ). The switching element ( 10 ) comprises a micro switch ( 16 ) including a stationary part and a movable part ( 30 ). The stationary part of the micro switch ( 16 ) is coupled to the stator element ( 20 ), while the movable part ( 30 ) of the micro switch ( 16 ) is rotatable around and shiftable along the same axis and coupled to the rim element ( 14 ). The micro switch ( 16 ) includes an encoder for indicating a rotation left or right and a shifting of the movable part ( 30 ) of said micro switch ( 16 ). The switching element ( 10 ) comprises at least one sensor antenna ( 18 ) forming a part of a capacitive touch sensor.

First claim

The invention claimed is:

1. A switching element for a control device, comprising:
a rotatable and shiftable rim element that is rotatable around and shiftable along the same axis,
a stator element rotatably and shiftably coupled to the rim element,
a micro switch including a stationary part and a movable part, the stationary part being coupled to the stator element, the movable part being coupled to the rim element and being rotatable and shiftable therewith about and along said axis,
the micro switch comprising an encoder for indicating rotation left or right and shifting of the movable part of said micro switch, and
a sensor antenna forming a part of a capacitive touch sensor, the sensor antenna being formed as a ring segment.

2. A switching element for a control device, comprising:
a rotatable and shiftable rim element that is rotatable around and shiftable along the same axis,
a stator element rotatably and shiftably coupled to the rim element, said stator element comprising a stator protrusion extending rearward and a cut-out formed in said stator protrusion,
a micro switch including a stationary part and a movable part, the stationary part being coupled to the stator element, the movable part being coupled to the rim element and being rotatable and shiftable therewith about and along said axis,
the micro switch comprising an encoder for indicating rotation left or right and shifting of the movable part of said micro switch, and
a sensor antenna forming a part of a capacitive touch sensor.

3. The switching element according to claim 1 , wherein the stator element includes a peripheral groove for receiving the sensor antenna.

4. The switching element according to claim 1 , wherein the rim element includes a seat element for receiving at least partially the movable part of the micro switch, so that relative rotation and shift between the seat element and said movable part is avoided.

5. The switching element according to claim 1 , wherein the movable part of the micro switch is a shaft rotatable around and shiftable along a longitudinal axis of said shaft.

6. The switching element according to claim 1 , wherein the rim element includes at least one first latch element, while the stator element includes at least one second latch element corresponding with said first latch element, so that the rim element is rotatably and shiftably coupled to the stator element.

7. A control device for a domestic appliance, wherein comprising the switching element according to claim 1 .

8. The control device according to claim 7 , wherein comprising a panel for receiving said switching element.

9. The control device according to claim 7 , wherein the panel includes at least one cut-out for receiving the switching element, said cut-out receiving the stator protrusion of the stator element.

10. A domestic appliance comprising the control device of claim 7 .

11. A switching element for a control device, comprising:
a rotatable and shiftable rim element that is rotatable around and shiftable along the same axis,
a cover element encasing a front side and a circumferential side of said rim element,
a stator element rotatably and shiftably coupled to the rim element,
a micro switch including a stationary part and a movable part, the stationary part being coupled to the stator element, the movable part being coupled to the rim element and being rotatable and shiftable therewith about and along said axis,
the micro switch comprising an encoder for indicating rotation left or right and shifting of the movable part of said micro switch, and
a sensor antenna forming a part of a capacitive touch sensor.

12. The switching element according to claim 11 , wherein the cover element includes at least one nut, while the rim element includes at least one tongue corresponding with said nut, so that a torque proof connection is formed between the cover element and the rim element.

13. The switching element according to claim 11 wherein the cover element is at least partially made of metal.

14. The control device according to claim 1 , said stator protrusion being ashlar-formed.

15. The control device according to claim 1 , wherein electrical leads of or from the micro switch penetrate said cut-out.
