ABSTRACT:
A method and apparatus are disclosed for providing co-planar connections to the terminal leads of a switching device from circuit elements located on opposite sides of a planar microstrip substrate. A through hole is provided in the substrate where the switching device is to be mounted. A conductive terminal is inserted through the hole. The terminal includes a portion contacting the circuit element on one side of the substrate and a portion extending through the hole to become substantially co-planar with the circuit elements on the opposite side of the substrate. A switching device is positioned in the hole to permit its leads to be connected to the extended portion of the terminal and to the microstrip circuit elements on the opposite side of the substrate.
