Abstract
A switching device is provided which is of a highly integrated structure and particularly adapted for a matrix arrangement of switch elements. The structure characteristically enables the switching device to be efficiently fabricated with maximum component density and minimum cost, and includes a base plate in the form of an integral combination of two insulating plates lying on each other, fixed contacts formed in an appropriate pattern on one of the insulating plates, and movable contacts formed integrally with spring strips supported on the base plate.
Claims9
A switching device arranged in a matrix array comprising:
- a first ceramic plate having a fixed contacts pattern of metalized layer arranged on one surface thereof;
- second ceramic plate formed with through apertures in positions corresponding to said respective fixed contacts arranged on said first ceramic plate, said first and second ceramic plates being laid on each other in closely adhering relation to form an integral base plate for the switching device;
- conductor means sandwiched between said first and second ceramic plates to connect to said fixed contacts with each other in each of the rows or columns of the matrix;
- spring means carrying movable contacts made of a magnetic material and mounted on said base plate so that said movable contacts are positioned directly opposite to said respective fixed contacts for cooperation therewith;
- a plurality of magnetic cores located adjacent said fixed contacts but on the opposite side of said first plate;
- and
- a plurality of energizing windings encircling said cores, said magnetic cores and windings being operable to selectively drive said movable contacts in an axial direction of said through apertures into contact with the corresponding fixed contacts.
