<p>The system has several different electrically operated tools, e.g. electric toothbrushes, with low-voltage accumulators and a charging station for connection to a high-voltage network and with a transformer. The tools are programmable and each is associated with a base station (5,5') with which it can be electrically coupled for transferring electrical charging and programming signals. The base station is reversibly connectable to the charging station (1) to supply the base station with a low voltage.</p> |
