ABSTRACT:
A miniature matrix is provided by coplanar conductive strips in a first row overlaid by a second row of coplanar strips. Both rows of strips are embedded within a molded substrate of elastomeric material which is sufficiently rigid to maintain the rows in spaced relationship. A plurality of recesses are provided in the substrate and are arranged in columns and rows. Each recess exposes a conductor in the first row and a conductor in the second row where such conductors cross each other. A conductive pin is inserted into a selected aperture to engage the corresponding exposed conductors, thereby making a cross point connection. The elastomeric material encircling the selected recess is elastically expanded upon insertion of the pin and exerts a resilient and residual retention force on the pin biasing the same into positive electrical contact with the cross point connected conductors.
