Abstract
Abstract The invention is a sensitive ribbon switch featuring reliable switch action even on a sharply curved surface. First and second conductive strips are separated by insulated members which are edge mounted in staggered space relationship. The transverse dimensions of the insulated members are considerably smaller than those of the strips. The switch is operative along its entire length due to the staggered arrangements of the insulator members and the switch will operate on a sharply curved surface without short-circuiting.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
121 words
Ribbon switch means comprising, a first conductive strip member having first and second edges, a second conductive strip member having first and second edges, insulator means being said strips, comprising discrete insulator members mounted along the edges of such strips in staggered space relationship, successive insulator members being mounted adjacent opposite edges of said strips, said insulator members being spaced along said edges so that a predetermined force applied perpendicular to said strips will cause said strips to contact each other along said first edges opposite an insulator member mounted adjacent to said second edges, said edge mounted insulator members having a transverse dimension substantially less than said conductive strip, and a transversely curved stiffening strip mounted below said lower member.
