1. An apparatus and system for automatic activation and de-activation of water flow, comprising:

  • One or more electrically operated, normally closed solenoid valves, each connectably interposed between a water inlet port and a water outlet port, and each of which, when energized, will open to activate the flow of water from its water inlet port to its water outlet port, and when de-energized, will close to de-activate the flow of water from said water inlet port to said water outlet port;

    One or more control circuits for actuating the one or more electrically operated, normally closed solenoid valves, said control circuits capable of being open and closed by means of one or more capacitance-sensitive electronic switches;

    One or more capacitance-sensitive electronic switches, each embedded on a circuit board, for opening and closing a control circuit, comprising one or more programmable microcontrollers each with at least two memory registers, one or more high-frequency, free-running, stable oscillators, one or more dip switches or similar timing control devices, and one or more low-signal dry-contact relays and associated relay contacts;

    One or more touch-sensitive pads that, upon coming in contact with a part of the human body, cause one or more of the one or more of the capacitance-sensitive electronic switches to open or close;

    Insulation for each of the one or more touch-sensitive pads to separate the one or more touch-sensitive pads from any mounting surfaces to which the one or more touch-sensitive pads may be affixed; and

    A means of regulating the voltage to the components of each of the capacitance-sensitive electronic switches that includes one or more split winding step-down transformers and one or more linear regulators.
