and in a column relative to the given column, switch A1, the first terminal Iß 1 of the switch

where χ is the ordinal number of the terminals of the B 1 and so on.

Switch is in the given row and column and the connections shown have a standardized ρ a step factor with a size between O (zero) scheme, so that if χ represents the number of a first and N. 5 switch connection, this with the corresponding If one examines this arrangement in matrix form, the first connection of a switch in the next, one finds that for the through-connection or another row in one of the first direction from an access point (the access point can either be connection points away from the direction and in towards the side of the first group or on the side of a column (x-p) in front of that, the second group of connections is connected) on io which as the direction Al-Bl-Cl-Dl-El actuates an outlet only a single switching point Al-Bl ... is defined, where ρ needs to be the priority factor. In the known arrangements it is designated and can assume any value from 0-x , however, with a series connection of groups. According to FIG. 1 a priority factor ρ is used in the actuation of at least two switching points required values of 1, with connections to be borrowed. This is a significant benefit. 15 switches to be made in the next lower line. In the arrangement according to the invention, the will be. The first connection points are to traffic from any switch to the traffic on the top of the matrix, and connections to the other switches are distributed with the result that to the first connections of switches in a switch with high traffic density not all consecutive rows in Direction down gears can occupy the other switches 20 made. When the first connection points are assigned. Another advantage is that if there were connections at the bottom of the matrix, the operational reliability of the arrangement would be high, because an error may occur in a switch block to the first connections of switches in one switch block, other lines in the upward direction during all or at least the largest part of the posed.

25 If x, the number of the first connection, 1 can be served to a limited extent, as before. carries, for example, for the switch A1

Seen from the manufacturing side, this is necessary

The effort involved is fairly low, since the wiring (x - d) = 1 - 1 = 0

The block assigns a total number of additional switches to be achieved. The special of 125 second connection points 1 ... 125 are located with regard to their first connections, however, because of the first connection points of the block to be described below, only 25 first repetition of the interconnection method of connection point 1 .. 15. These 25 first connector 60 blocks connected. The first connection 1 A 6 of a point are divided into five groups, ie five group-specific switches A 6, which are shown schematically for each switch in the top row. Decision half of the switch A 5 is attached, is with the speaking of the connection arrangement, each DIE first terminal of the switch 5 is 1,4 A 5 is connected; This first connection point for a different connection of the first connection 2 A 6 is connected to the third combination of 25 connection points outside the 65 circuit 2 £ 5 of the switch ES ; the third 125 second connection points available. Terminal 3 A 6 is connected to the first terminal 3D5 according to Fig.l only the connections switch D 5; the first connection 4.46 is for the first connections 1.41 ... 5Al of the one connected to the first connection 4 C 5 of the switch C 5

bound; the first terminal 5Λ6 is connected to the first terminal 555 of the switch B5 . These connections ensure that the first connection 1A 6 is connected to the first connection point 1, and the first connections 2 A 6 ... 5 A 6 are correspondingly connected to the first connection points 2 ... 5. F i g. 1 shows another row of switches A 6. .. B 6, but only connections to the first connections 1 ... 5 of switch A 6. Further rows of switches could be added, the interconnection then simply repeating the scheme of switches A 1 ... £ 5.

The blocks of switches according to FIG. 1 more blocks can be added to increase the capacity of the switch system. The addition of another block is similar that according to FIG. 1 would result in another 25 first connection points, which between other 125 second Connection points are divided. In this case the blocks are quite separate, although preferably that same interconnection procedure is used.

In the case of the matrix according to FIG. 1 are from the first connections of the switches in a row to those the switch in the next adjacent row, which is shown in FIG. 1 is the next bottom row, Connections made. If desired, a connection could be made to the first port of a switch take place in a subsequent row or line which is not the next following row.

In an optional embodiment of the invention, switches with a coordinate arrangement of seven first and second terminals are used. Using the same notation as above for the 5 x 5 switches, F i g shows. 3 the interconnections for the first connections of the switch Al. Other first terminals of other switches are interconnected in a similar manner.

F i g. Figure 4 shows similar interconnections for 9x9 switches.

According to FIG. 3 and 4 a priority factor of 1 is used.

The advance from column to column can take place in the manner described from the right of A through B, C, D to E , if P = I , or the advance can optionally take place to the left from A through E, D, C to B , although the first method is preferable for reasons of clarity.

If ρ is equal to any number other than 1, it must be noted that advancement in one direction is evaluated positively and in the other direction negatively. Although this has basically no influence, for the sake of clarity it is assumed that the positive direction is to the right and the negative direction is to the left.

Let switch A 1 from FIG. 1 considered assuming an advance factor of ρ = 2. Then x - p = l - 2 = - 1 if χ = 1, so that the first connection IAl is connected to the first connection 1E2 of the switch E2 ; χ - ρ = 2 - 2 = 0 when χ = 2 , so that the first terminal 2Al is connected to the first terminal 2,42 of the switch A 2 ; x - p - 3 - 2 - 1, if χ == 3, so that the first terminal 3 A1 is connected to the first terminal 3B2 of the switch B2 .

Consider the switch 41, 41 of FIG. 1 and an advance factor ρ of the value 5. Then χ - ρ = 1 - 5 = - 4 if χ = 1, so that the first terminal 1.41 is connected to the first terminal Iß2 of the switch B2 ;
x - p = 2 - 5 = - 3 when χ = 2 , so that the first terminal 2,41 is connected to the first terminal 2C2 of the switch C2;
χ - ρ = 3 - 5 = - 2 when χ = 3, so that the first terminal 3Al is connected to the first terminal 3D2 of the switch D2 ;

ίο x - p = 4 - 5 - - 1 _; if χ = 4 , so that the

the first terminal 4Al is connected to the first terminal 4 E2 of the switch E2 ;
χ - ρ = 5 - 5 = 0 when χ = 5, so that the first terminal 5.41 is connected to the first terminal 5 ^ 4 2 of the switch A 2 .

For switch A 1 of FIG. 1 and an advance factor ρ = 3 follows:

x - p = 1 - 3 = - 2 when χ = 1, so that the first terminal 1,41 is connected to the first terminal IjD2 of the switch D 2 ;
x - ρ = 2 - 3 = - 1 when χ = 2 , so that the first terminal 2 A 2 is connected to the first terminal 2 E 2 of the switch E 2 ;

χ - ρ = 3 - 3 = 0 when χ = 3, so that the first terminal 3, 41 is connected to the first terminal 3 A 2 of the switch A 2;
* - p = 4 - 3 = 1 when χ = 4, so that the first terminal 4.41 is connected to the first terminal 4ß2 of the switch B2 ;
χ - ρ = 5 - 3 = 2, if χ = 5, so that the first terminal 5.41 is connected to the first terminal 5C2 of the switch C2,

F i g. Figure 5 shows the interconnections of the first terminals of switch A1 of Figure 5. 1 using a priority factor of 4. F i g. 6 similarly shows interconnections using a precedence factor of 5. FIG.

The considerations regarding the value of ρ and the positive and negative directions of advance must be maintained across one block, but may be different for other blocks.

In any block of the aforesaid embodiments mentioned, the interconnection of the first terminals of switches β1, Cl, Dl, El is similar to that of the first terminals of switch A1; the interconnections between switches in adjacent rows are similarly similar. Thus, the interconnections have a standardized scheme so that a standardized preformed terminal pad can be used in practical manufacture.

A switch system according to the invention is for use as a switch stage in an automatic Telephone switching center suitable and can be switched so that the second connection points with Participants and the first connection points are connected to other switch stages. The system can also be used as a final selector in an automatic telephone exchange. In this in the latter case the connection points can be connections from a previous switch stage, and the second connection points can be to the subscribers, other switching centers and the like show running points.

Telecommunications from any counter

is distributed over the entire telecommunications traffic of other lines or rows, so that a switch with a high level of telecommunications traffic, all those available for the other switches Can "employ" connection points. Furthermore, the security of the system is relatively high because Errors can occur in a block of switches, while on the other hand a minimum proportion of

ties to all or the majority of the second connection points are maintained, which are connected to the block.

Control devices to be used in conjunction with the switch system according to the invention can be designed in any known manner and are therefore not special described.
