Abstract
The invention is directed to a control element, particularly for automotive electronics, having programmable haptics. Moments of force or a variation of the friction moments are formed on a control element by dynamically adapting the operative currents of electromagnetic arrays in dependence of the adjustment path. The force/path behavior (tactile feedback) of the control element can be modified at will during use so that the actuation forces for different operative functions can be varied. The tactile feedback of the moments of force on the control element takes by way of a locking piece, which, for example, can be comprised of at least one locking disc and a spring, which can be rendered active or inactive via an electromagnetic array.
