Wiring arrangement switching body with associated circuit board and body

摘要

A body (1) for a wiring arrangement has switching path conductors forming a specific pattern each conductor (1a,1b,1c,1d,1e) having a particular shape and sepd. from each other by an insulating resin (2). The switching pattern appears on both faces of the body (1). Prodn. of a wiring arrangement body (1) involves: (a) cutting grooves in a plate of highly conductive material to give a specific switching pattern; (b) casting an insulating resin into the grooves; (c) cutting the conductive material away normal to the base of the grooves to reveal the conductive material pattern (a1-1e) surrounded by resin (2). Other process variations are also claimed. The circuit board itself is also claimed.
