摘要： A finger-pressure actuated matrix switch assembly includes a map overlay and generates a binary coded signal corresponding to the coordinates of the point of application of pressure to the map. The assembly comprises a housing with a slot for positioning a replaceable map card in operative position and a storage chamber for a plurality of such map cards. Each of the map cards is edgenotched with a unique code identifying that card, and switches supported on the housing are actuated by these notches when a map card is inserted into its operative position to generate a binary electrical signal corresponding to that code. The matrix or grid is formed by orthogonally related sets of printed conductors on stacked boards spaced apart by resilient strip separators formed directly on one of the boards. Logic circuitry for converting the coordinates of contacting conductors into binary digits is carried on a single pluggable board detachably connected to the matrix boards for quick replacement to facilitate maintenance and repair.
