Control device for twinned washing and/or maintenance station for motor cars

The present invention has the object SB-tandem cleaning and / or nursing stations to develop so that instead of previously two coins only one coin for the acceptance of coins or a corresponding balance is used by prepaid cards. As a result, the corresponding costs are saved both during manufacture and during maintenance. An additional advantage of the invention lies in the fact that a space gain is realized in partially confined spaces. By means of a corresponding selection switch, it is selected for which place, A above B, the credit in the form of a coin or by reading out a prepaid card and storing for the relevant place A or B is credited. This means that due to the present invention, only one coin is needed for the verification of the credit for a SB tandem cleaning station, resulting in a corresponding savings potential.
