  • Patent number: 9202644
    Abstract: A cord switch including a cord switch main body including a hollow tubular member having elasticity and electrical insulating property and a plurality of electrode wires provided to face each other with an interval at an inner surface of the tubular member and spaced from each other by the elasticity of the tubular member, and a mounting member having an elastic modulus greater than an elastic modulus of the tubular member and being provided along the cord switch main body. The cord switch also includes a strip-shaped impact absorption member having an elastic modulus lower than the elastic modulus of the tubular member, which is interposed between the cord switch main body and the mounting member.

  • Patent number: 7534957
    Abstract: A cord switch 1 has wire electrodes 12A, 12B spirally arranged along an inner surface of a hollow part 10 of a hollowed insulator 11 in a longitudinal direction such that the wire electrodes do not electrically contact with each other, an outer electrode 13 provided around an outer periphery surface of the hollowed insulator 11 and jacketed with an insulating layer 14. An electrostatic capacitance is formed between the outer electrode 13 and a wire electrode for grounding, and a floating electrostatic capacitance is formed between the outer electrode 13 and the earth. The close approach of the human body to the cord switch 1 can be detected in a non-contact manner by measuring the alteration in the electrostatic capacitance.
