Abstract
The invention is directed to a control element, particularly in a central control unit. A magnet clamping system is integrated into a control element in order to render the function “slider setting” unequivocal. In addition to an actuator head that is positioned on a shaft, which is guided in a cylinder, for example, and at least one circuit board having LEDs, the control element includes a magnetic device having a designated magnet, which is functionally connected to the actuator head. When the actuator head is moved vertically by sliding, the magnetic device lifts off the magnet due to tilting, which causes a code disc attached to the actuator head to be brought into an inclined position such that a light flow on the light barriers formed by the LEDs is disrupted and/or opened up. In a further embodiment, this control element also includes press and rotate functions.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
