Selecting switching functions using screw-force, on modules having traces

Abstract

This invention can be used as mini-micro-switching, up to macro switching. An electronic module having several input copper circuit traces, and several output copper traces, or wires, with some traces having disconnects, consisting of drilled holes, which can be bridged by conductive fasteners. This invention is also solving switching of differing functions both in the industry, and after that the product is in the market and the customer requests switching options. Selecting a switching options can be accomplished on a module, by first remove a conductive fastener from one position and attach the fastener in a second position on copper traces. Where the fastener is removed and not re-inserted, an open circuit trace occurs. Thereby accomplishing: selecting, reversing, or switching of one, or of a multiple of circuits.

Claims
