IPC: H01H67/30
Filed: 1977-10-21
Abstract: PURPOSE: To ensure the high-efficiency cumultative selection and to simplify  and minimize the structure of the electromagnetic coordinates selector, by controlling the open/close of the selected matrix-type electromagnetic switch element.  
     CONSTITUTION: Permanent magnet 1 of each electromagnetic switch element 10 is fixed to insulator panel 11, and semi-hard magnetic substance 2 is fixed to insulator panel 12 respectively. At the same time, horizontal and vertical coils 13 and 14 which are coiled round in common to all suide elements with every line and row are prouided. Then ether one of coils 13 and 14 is selected each to be applied with -2I current pluse, so the magnetization state of all switch elements contained  in the selected horizontal and vertical coils becomes to point 18, and thus all  switches are released. After this, the current pulse of I is applied to coil 13 and  14, so only the switch element where the horizontal and vertical coils cross each  other is excited with the current of 2I. And the magnetization state is inversed to  become to point 17 and to operate. The other switch elements are kept released
