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.
