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.
