Abstract: The operating element (16) of a sanitary fitting has a temperature slide (20) and a flow rate slide (22). These two slides (20, 22) are movable back and forth along a first movement path (40) and a second movement path (42) respectively, in order to set, on the one hand, the temperature of the water and, on the other hand, the flow rate of the water. Sensors (54, 60) detect the location and the position of the temperature slide (20) and of the flow rate slide (22) and deliver corresponding temperature signals and flow rate signals to the electronic controller (56). This controller controls the valve bank (68) in such a way that water with the desired temperature and the set flow rate flows out of the sanitary fitting through the water outlet (28). Square or rectangular designs and a fitting (312) having virtual slide controls (340, 342) are also possible.
