ABSTRACT:
An essential contactless control means is provided for operating a device which mixes and discharges two fluid media such as water faucet for discharging a temperature controlled mixture of hot and cold water. In the case of the water faucet, for example, the hot and cold water flow to the mixing chamber of the faucet is controlled by a pair of magnetic valves, preferably operated by an electronic circuit, which opens the valves when the hand or an object approaches the control antenna of the circuit. In this device, expensive separate additional controls are eliminated by providing the magnetic valves with manually adjustable knobs.
