US 5,728,983 A · Elongated tube-like pressure sensitive cable switch

Abstract

A pressure-sensitive cable switch includes a pair of metallic conductors arranged in opposing relation to one another on the neutral axis for bending within the cross section of a rubber tube, and extend in the longitudinal direction of the tube. A pair of belt-shaped electrodes made of conductive rubber material or other conductive materials and embedding the metallic conductors therein, are disposed to oppose each other on the inner circumferential surface of the robe with respect to the neutral axis for bending. The electrodes extend in the longitudinal direction of the tube. Therefore, an erroneous operation of the cable switch at a part where the switch is bent is prevented, and furthermore the cable switch operates while coping with a wide range of load application angles.
