ABSTRACT:
A keyboard switch construction in which contacting surfaces in spaced apposition on resilient, flexible, electrically non-conductive laminae are prevented from making contact in the absence of outside pressure by ribs formed in the material and substantially surrounding the conducting surface on one lamina. The switch construction is used in a control panel arrangement in which pilot and operative components are separately mounted and are associated by printed circuitry carried on a flexible insulating strip which may be physically continuous or may be electrically continuous using a multi-contact connector to interconnect two physically separate halves of the sheet.
