MULTIPLE SWITCHING ELEMENT FOR INTERCONNECTING A GREAT NUMBER OF MULTIPLE TERMINALS

摘要

The invention relates to a multiple switching element for connecting a large number of multiple terminals fed, for example, through a bus-oriented rear wall board. The invention provides for the connection of a multi layer circuit board, which has a number of plug strips on opposite sides corresponding to the number of multiple buses to be linked, and internally has a number of lateral connecting conductor layers, in different planes, corresponding to the number of buses of a multiple bus minus 1, through contacts being made between the conductors of a lateral connecting layer and in each case one of the buses of a multiple bus. According to one advantageous further development, the lateral connecting conductor layers are continued up to the edge of the board so that additional switching elements can be looped into the bus lines which are to be linked to one another.
