Each reed has a fixed end sealed in the capsule and a flat movable portion with side edges substantially parallel to one another for a predetermined length and tapered toward one another from the end of the predetermined length to the tip of the movable portion. The reeds are positioned so that the movable portions overlap one another by an overlap length and define an overlap area which is less sensitive to variation in overlap length than a conventional sealed contact having reeds cut substantially normal to the parallel side edges. | ||||||
| 159 | Crosspoint elements and electromagnetic coordinate selection devices utilizing the same | US54919375 | 1975-02-12 | US3928828A | 1975-12-23 | KATO KATSUHIRO; SUZUKI HIDEO; YANO NORIO |
| The crosspoint element comprises a reed switch comprising a pair of reed pieces having cooperating contacts and an exciting winding for operating the contacts. Each reed piece comprises a core conductor of a first magnetic material and a sheath made of a second magnetic metal having different coercive force from that of the first magnetic metal. When a release pulse current is passed through the exciting winding, the crosspoint elements permit a large permissible variation in the peak value of the magnetomotive force required for holding the reed piece at a definite state of mangetization. The crosspoint element is especially suitable to use as a selection element of an electromagnetic coordinate selection device.
