Omnidirectional response cable switch
First Claim
1. An omnidirectionally responsive cable switch which comprises a tubular outer cover made of an insulating material and two separate conductive rubbers of irregular shape, said separate conductive rubbers being fixed on the inner surface of the outer cover leaving an air gap therebetween, said separate conductive rubbers being apart from each other, and said outer cover being capable of being distorted together with the conductive rubbers so that the separate conductive rubbers contact each other when compressive pressure from any direction is applied thereto at any point on the outer cover, thereby forming a switching contact therebetween, said air gap being substantially S-shaped in cross-sectional view having two portions extending towards the outer cover and a third portion interconnecting said two portions, said two portions and said third portion being of substantially uniform width.

Abstract
This invention provides an omnidirectionally responsive cable switch (5) capable of snake-like or twisted wiring or layout and comprising a tubular outer cover (1) made of an insulating material and 2-4 separate conductive rubbers (3a-3d) fixed on the inner surface of the outer cover leaving an air gap (2) therebetween, the separate conductive rubbers being spaced apart from each other, and the outer cover being capable of being distorted together with the conductive rubbers so that the separate conductive rubbers may contact with each other when substantial compressive pressure is applied thereon at any point of the outer cover, thereby forming a switching contact therebetween. The air gap (2) may be substantially of a cross-shaped, Y-shaped, V-shaped, S-shaped, or arrow-head-shaped form. The omnidirectionally responsive cable switch may be further protected or guarded by a reinforcing member or material.
