Sanitary fitting with a joint

A sanitary fitting comprising:

• a mixing valve unit with an input for a cold water line and a hot water line and an output on which a mixed water line is connected;
• a water outlet connected to the mixed water line;
• and
• a joystick to steplessly choose at least the water temperature by controlling the mixing valve unit, wherein the joystick contains a joint arrangement including:
• a support connection piece that defines an abutment face that is approximately flat;
• a joint part that rests flat against the abutment face by way of at least an approximately flat mating face, and defines a neutral position;
• a spring that surrounds the joint part on the outside, and includes a first end and a second end, wherein the first end of the spring is supported against the joint part, the second end of the spring is fixedly supported relative to the abutment face, and the spring uses a spring force to push the joint part against the abutment face by way of the mating face;
• and
• a rod-like extremity being in the form of an operating lever and arranged on the joint part at a fixed angle in relation to the mating face, with the joint part maintaining the neutral position when an external lateral force acts on the extremity until the lateral force exceeds a limit value that is predefined by the spring, the abutment face and the mating face and, in the process, partially lifts the mating face away from the abutment face, and the flat contact between the abutment face and the mating face becomes at least one of either a line contact and a point contact.
