ABSTRACT:
A shower head contains two shower devices, which can be alternately operated with the aid of a changeover device. One shower device contains a row of shower holes. On switching from the first to the second shower device, a pin is inserted in each shower hole and has approximately the same diameter as the shower hole. Thus, during each changeover, there is a cleaning of the shower hole from the inside, which leads to a removal of deposits and contamination.
