The operating element has an armrest (1) and three or more mini levers (3,4,5,6,7) which are arranged so that exactly one finger of one hand of the operator is assigned to each mini lever and with the arm resting on the armrest the finger tips of the hand hover precisely over the relevant mini levers. At least one, and preferably each, mini lever has rubber coating in the touch area for increasing the friction. |
