ABSTRACT:
A hemispherically shaped membrane switch assembly for attaching to generally hemispherical surfaces such as cathode ray tubes is disclosed. Also disclosed are a method and apparatus for forming the assembly. The assembly is comprised of two layers of transparent film having spaced-apart conductors on the internal surfaces of both layers. The internal surfaces are separated by spacing means, the spacing means being discontinuous at the switch sites. The conductors on the two layers cross and are spaced apart at the switch sites. The assembly is hemispherically formed to the same radius as the hemispherical surface on which the assembly is to be mounted. The assembly mounts flush to the hemispherical surface and conforms uniformly to its surface thus reducing distortion and parallax.
