Description

The invention relates to the field of electrical engineering and can be used in radio systems for switching and memorizing a group of inputs to a group of outputs.

Matrix commutators with a fully accessible circuit, consisting of multiwinding polarized relays, are known for switching and memorizing a group of inputs to a group of outputs with key controls.

However, such switches allow switching at the same time: 1 nd multiple incoming lines to one outgoing line.

The aim of the invention is to provide interlocking by switching only one incoming line with one 1-way line.

To do this, the start of one-column switch-on windings through decoupling diodes are connected with a common point to the corresponding switch control circuit vertically, and the ends of the switch-on windings of all relays of one row are connected with a common point to the normally open contact of the corresponding switch control circuit horizontally. The beginning of the first windings of disconnecting all relays of one column through decoupling diodes is connected with a common point to the corresponding switch control circuit vertically, and the ends of the first windings of disconnection of one row are connected

a common point to the normally closed contact of the corresponding control circuit of the ODOM switch horizontally. The beginning of the second disconnecting windings of all relays of one column through decoupling diodes is connected with a common point through the diode matrix to all control circuits along the vertical, except its own, and the ends of the second disconnecting windings of one row are connected with a common point to the normally open contact of the corresponding control switch horizontally.

The drawing shows a schematic diagram of the proposed switch.

It consists of multiwinding polarized relays 1 (in principle, three windings are needed for the circuit, however, such relays are not manufactured by the industry and four-winding relays are used in the device), it contains circuits 2 and 3 of the control of the switch vertically and horizontally, and the diode matrix 4. V relay 1 winding circuits include three decoupling diodes 5.

The start of the turn-on windings and the first turn-off relays of the relay 1 are vertically through decoupling diodes 5 with a common point connected to the switch control circuits vertically. The start of the second disconnecting windings through decoupling diodes 5 with a common point is output to the diode array 4.

The ends of the turn-on windings and the second turn-off windings of the relay 1 are horizontally shared by a common point, the normally open contact ends, and the ends of the first windings are turned off by a common point to the normally closed contacts of the switch control circuit horizontally.

The operation of the circuit is illustrated by the example of switching the first incoming line to the first outgoing line. When the first circuit 2 is energized by the switch control vertically and the first switch control circuit horizontally (the drive time must be not less than the relay response time), the electric current flows through the switch on winding of the relay located at the intersection of the first column and the first row of the switch and through the switch off windings of all the remaining relays included in the first column and first row.

In this way, the first incoming line is switched to the first outgoing line with the first incoming line disconnected from the other outgoing lines and other incoming lines from the first outgoing line.

When connected to the comma of the first outgoing line, the input line switches on the relay located at the intersection of the second row and first column, and disconnects the remaining relays of the second row and first column. When a free incoming line is connected to a free outgoing line, the previously switched relays are not disconnected.
