ELECTRICAL SWITCHES
First Claim
1. An electrical switch including a first flexible elongated conductor in the form of a conductive wire, a second flexible elongate conductor in the form of a conductive braid, and a resilient, deformable insulating sheath spacing said first conductor, throughout its length, from said second conductor said sheath encircling said first conductor, the material of said sheath being loaded with conductive particles, whereby compression of said sheath in a direction to decrease the spacing of said first and second conductors establishes a conductive path within said sheath between said first and second conductors.

Abstract
An electrical switch including a first flexible elongated conductor and a second flexible elongated conductor coaxial with the first conductor. An insulating element which is both resilient and deformable spaces the first conductor from the second conductor along the whole length of the first conductor, and the insulating element is loaded with conductive particles. The nature of the insulating element containing the conductive particles is such that compression of the element in a direction to decrease the spacing between the first and second conductors establishes a conductive path within the element between the first and second conductors.
