Abstract

1506078 Reed relay matrix; printed circuits INTERNATIONAL STANDARD ELECTRIC CORP 17 Aug 1976 [26 Aug 1975] 34174/76 Headings H1N and H1R A reed relay matrix on a printed circuit board 1 has the printed circuit connections 2 provided with a layer 4 of ferromagnetic material. The connectors may extend on both sides of the board and the hole 5 through which a reed contact unit 5 extends may be lined with ferromagnetic material (Fig. 3, not shown).
