1. A device for connecting in series between a source of electrical power and only an appliance'"'"'s power connection which regulates the supply of electrical power to the appliance in response to a mere touch of the appliance, said device comprising;

  • (a) an electrical connector for interposing the device between the current-carrying components of the appliance and the power supply;

    (b) an electric power regulator for increasing or decreasing the electric power provided to said appliance;

    (c) an electrical impedance network for electrically including the appliance within the impedance network when the device is connected between the source of electrical power and the appliance which impedance network has a very low impedance to power supply frequencies and a high impedance to frequencies higher than power supply frequencies;

    (d) an electronic sensing circuit for sensing the distributed capacitance to ground characteristic of the appliance as an electrical signal;

    (e) an electronic signal processing network to condition the said electrical signal; and

    (f) a memory and control circuit network to convert changes in said electrical signal into control signals for said electric power regulator.
