Abstract: A coordinate electrical switch construction comprising a pair of flexible insulating sheets each havng pierced therethrough a coordinate array of "U" shaped magnetic contact elements arranged to have corresponding legs in opposing, spaced-apart registration. Winding means coupled to the contact elements in each set of coordinates on each sheet are coincidently energisable to selectively magnetize a pair of elements at a crosspoint to bring opposing legs into electrical contact against the flexion of the sheets. The contact elements are multiplied together in one and the other sets of coordinates on respective sheets to provide signal path halves which are completed upon contact leg closure at a crosspoint. The contact elements are of a remanent magnetic material so that closure is maintained after termination of the energizing step. Release of selected crosspoint elements is achieved by reverse energization of the defining winding means.

Abstract: A coaxial cable switch comprising a plurality of sealed reed, magnetically responsive switches serially connected in alternating directions which switches act as the inner signal path of a coaxial conductor. The outer coaxial conductor consists of a copper "corrugated" sheet within the adjacent and oppositely facing channels of which the individual switches are respectively positioned. The open sides of the channels are covered with metallic tape by means of a conductive adhesive and a single winding encircles the structure for the simultaneous operation of the reed springs.
