With the means of the invention, the control apparatus can correspondingly respond anytime to a change of the input signal. In an especially advantageous configuration, the means of the invention include a lower internal current draw than the activated control apparatus. According to the invention, one obtains a high operational reliability of the control apparatus without an excessive energy consumption because the means of the invention have only a low internal current draw and the control apparatus with the higher internal current draw is activated only as required (change of the input signal).
