ABSTRACT:
An operating mechanism for a fluid flow shifting valve of a sanitary mixing faucet assembly or the like of, for example, a bathtub and shower, which raises or lowers a flow shifting valve stem guided in the mixing faucet body so as to shift the fluid flow between two outlets, comprises an operating lever pivotally connected to the valve stem and also attached pivotally to a preferably rodlike, centrally located pivot bearing, wherein the lever arm of the operating lever is proportioned so that a reduced applied force is sufficient to effect a shift in fluid flow. Advantageously the operating lever may be provided with a press contact or a lever cap attached to its top for ease of operation. The operating mechanism is essentially integrated in the mixing faucet body so that it does not protrude significantly.
