Water faucet with scald protection

A water faucet (1) having an adjustable cartridge (2) for the infinitely variable mixing of a cold-water flow and a hot-water flow to form a mixed-water flow, having a first adjustability (3), by means of which the mixing ratio of cold water and hot water in the mixed-water flow can be set, and having an operating lever (4), which is connected to the first adjustability (3) of the cartridge (2) via a transmission mechanism (5) such that the mixing ratio of cold water and hot water in the mixed-water flow can be set by a temperature setting motion (6) of the operating lever (4), wherein the temperature setting motion (6) is a rotary motion about an axis of rotation (19), wherein the transmission mechanism (5) has at least one stop (7), which limits a movement of the first adjustability (3) of the mixing ratio in the direction of more hot water at a threshold setting (8), wherein the stop (7) is designed such that the operating lever (4) is brought into an unlocking position (21) by an unlocking motion (11) deviating from the temperature setting motion, such that a further movement in the direction of more hot water is made possible beyond the threshold setting (8).
