Abstract

The invention relates to switching technology and can be used for switching high frequency circuits. The aim of the invention is to enhance the operational capabilities by increasing the crosstalk. Each switch cell includes a two-winding polarized relay 1 with switching contact 2, two diodes 3, horizontal 4 and vertical 5 turn-on busbars, horizontal 6 and vertical 7 turn-off busbars, first drive element 8 with change-over pin 9, insulating insert 10, the second drive element 11 with a switching contact 12 and an insulating insert 13, a power source 14, vertical 15 and horizontal 16 buses controlling the elements of the drive, tires 17 and 18 rows and columns, jumper 19. Row and column tires aklyucheny in screen. When applying to the horizontal 4 and vertical 5 bus switching on the corresponding control signal cell, the relay 1 of this cell triggers and closes its contact 2, through which drive elements 8 and 11 are connected, connected through insulating inserts 10 and 13 to switching contacts 9 and 12. The pins close to form Bx.1 and Vyh.1 of the high-frequency matrix. 3 il.

The invention relates to switching technology and can be used for switching high frequency circuits.

The aim of the invention is to expand the operational capabilities {guided by increasing the crosstalk.

FIG. 1 shows the electrical circuit diagram of the switch; in fig. 2 and 3 - high-frequency matrix, embodiments.

The switch contains N switching cells, each of which includes a double-winding polarized relay 1 with a switching contact 2, two diodes 3, horizontal 4 and vertical 5 turn-on busbars, horizontal 6 and vertical 7 turn-off busbars, each cell also includes the first element 3 a drive with a switching contact 9 and an insulating insert 10, a second drive element 11 with a switching contact 12 and an insulating insert 13, a power supply 14, a vertical 15 and 16 horizontal horizontal drive elements control buses, Rows 17 and columns 18, jumper 19 rectangular box-shaped screens of rows 20 and columns 21, metal plate 22.

The switch works as follows.

For example, to connect input 1 to output 1 on the horizontal 4 and vertical 5 buses, a turn-on signal must be given. Relay 1 triggers and closes its contacts 2, through which the elements are then turned on with water 8 and 11 connected through insulating inserts 10 and 13, respectively
