Patent number: 7534957Abstract: 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.Type: GrantFiled: October 31, 2006Date of Patent: May 19, 2009Assignees: Hitachi Cable, Ltd., ASMO Co., Ltd.Inventors: Akira Yamaura, Yoshikazu Hayakawa, Tatsuya Ohtaka, Takashi Aoyama, Tomiya Abe, Masaaki Shimizu, Manabu Kato
