Functional 12a is provided for the control of an individual cooking position in the cooking field (figures 1 to 3a). The control means 14a are arranged in a functional state in housing areas of the control means 62a, which are formed by round recesses 52a in the support unit of control means 10a. The recesses 52a are practiced by means of a process of transformation by chip removal in the support unit of control means 10a, and in particular by a milling process. The control means 14a are projected in the functional coupled state shown beyond a lateral contour 76a and beyond a cover surface 78a of the control means support unit 10a and in particular with an extension of approximately 5 mm, so that a command of the control means 14a is possible on its front side. The lateral contour 76a forms a leading edge of the control means support unit 10a which is directed to a user that is arranged in front of the cooking field control device. The control means 14a are secured in the functional coupled state in radial direction 74a to their axes of rotation 32a in the direction of the lateral contour 76a by means of the support unit of command means 10a or are limited in their movement and in concrete, respectively, by a marginally circular area of the housing areas of the control means 62a of the support unit of control means 10a. The marginal areas of the housing areas of the control means 62a extend with respect to the axis of rotation 32a of the control elements 14a, respectively over more than 180 ° and over less than 360 °, whereby the control means 14a are secured, respectively, in all radial directions 74a towards the axis of rotation 32a between the housing areas of the control means 62a or are limited in their movements and in spite of everything an advantageous control in the partial areas of the control means 14a projecting above the lateral contour 76a.

The control means 14a are guided in the housing areas of the control means 62a in their rotating movements 18a and their rotation axes 32a, by means of which a regulation of the respective cooking stations can be made. To perform control functions that deviate from the rotary movement 28a, the control means support unit 10a has contour elements 16a for performing tilting functions (figures 3 and 3a). The contour elements 16a have, respectively, an inclined surface arranged in a bottom area of the housing areas of the control means 62a, which forms in a functional state of the support unit of control means 10a in front of a plane horizontal 22a at an angle 24a of approximately 20 ° and which extends in a ring shape around a base surface 28a of the function field 12a which is formed by a circular surface and which is arranged in the same way in the area of the bottom of the accommodation area of the control means 62a.

During a tilting movement, a signal resulting from an increasing distance parallel to the axis of rotation 32a between the grinding means 70a and the MR-sensors is evaluated by means of the evaluation unit 38a over an area 42a that is opposite the activation zone 40a.
