  • Patent number: 9739040
    Abstract: A sanitary fitting having at least one first actuating element, in particular for setting the temperature and/or volume of mixed water, and having at least one second actuating element for setting the volume of hot water. In order to set the volume of hot water, a valve element, in particular a solenoid valve, which is electrically controllable by the second actuating element, is arranged in the hot water flow path.

  • Patent number: 9085879
    Abstract: An electronic control switch with at least two operating states for water faucets. The control switch has at least one control section, a base section, and a guide for a motion of the two sections relative to one another. At least one sensor is located in one section and at least two magnets are located in the other section, or alternatively at least two sensors are located in one section and at least one magnet is located in the other section, and each magnet associated with an operating state enters a detection region of a sensor at least at times in the course of the relative motion. The magnets at least have different magnetic field strengths or different spacings from the sensor.
