  • Scale having a capacitive proximity switch with an electrode
    Publication number: 20040000438
    Abstract: A scale is provided which includes a support plate for holding a mass to be weighed, and an electrical switch device for selecting or dialing a function of the scale. The electrical switch device has a capacitive proximity switch with an electrode disposed on the support plate. The capacitive proximity switch monitors an ambient capacitance of the electrode, and reacts solely to the approach of an object (such as a human foot) whose dielectrical properties are different from those of the stationary environment of the proximity switch.
