Abstract
The present invention relates to a control element having a rotary knob (4), having a magnetic circuit and having at least one coil (1). The rotary knob (4) is supported so as to be rotatable with respect to at least a part of the magnetic circuit, the gap (5) present between the rotary knob (4) and the magnetic circuit is filled with a magnetorheologic fluid, and the coil (1) is arranged to exert a variable braking action on the rotary knob (4).
