Electrical connection raster for electronic chess board - formed with matrix of isolated field element responding to chess figures placed on surface

摘要

A chess board field (SF) is subdivided into a number of electrical elements (TNM0 isolated from each other. Each field element consists of a line raster (1) with external contacts that provide couplings (K1-Knm). The field elements respond to chess figures placed on the surface of the board that interact with the line raster. The underside of the figures has resistors linked to contact points set out at the corners of a triangle. ADVANTAGE - Provides interconnection of isolated field elements to common contacts.
