The invention relates to automation and switching technology; n can be used, strictly in the control of switching devices.

The purpose of the invention is the innovation of reliability.

In the drawing, an electrical circuit of the matrix switch is shown.

The matrix switchboard contains a relay element 1, which can be a relay in the ground with a winding 2 and a switching device with a contact ground 3 with 1 time delay when triggered, the first 4 and second 5 lines of control and the closing gyuttsy 6 unrail stolbnami, and 15 groups 7–1 of the supply diodes, 11al 1pcd relay with windings 12–1 and 12–2 nKJH04eHH i and disconnection and busbar: 13, 4 gp. One pins of the I2-I windings of polarizing polarized relays in each with 1 rock of 1) LED are connected to one terminal of the corresponding external locks of the 1 st contacts 4 of the control lines, the other winding pins of 12-1 connections in each column are combined through decoupling the diodes of the first group 7, some conclusions of the windings 12-2 of all polarized relays united were connected, the other conclusions of the windings 12-2 were interconnected in each column are connected through the connecting diodes of the second group 8 n to connect the same conclusions of the corresponding contact terminals 6 controls They are joined by columns, and in each row they are connected via third group 9 diodes and a plug-in diode (s to one of the codes of the corresponding second closing contacts 5 of the row control, one terminals of the closing contacts 6 of the column controls are combined via the connecting fourth diodes of the fourth rpyiHibi and connected to one output windings 2) of a 5-element element 1, the other output of which is connected to one power supply bus 13, one of the outputs of the second closing contacts 5 of the line control contacts are connected through isolating diodes 11 of the same group and are connected to the union. other pins 3af fbrKaionmx contacts 6 column management.

The efficiency of the control of the contact of the control unit of the strcg-w and columns can be performed, for example, in the form of control keys 15 and 16 (toggle switches, buttons), and the switches 4 and 5 can be mechanically connected with each other,

Matrix com ator works in the following way.

The inclusion of a polarized relay, located at the intersection of, for example, the first row and first column, closes control key 15 and 16, respectively, with the first row and the column. This closes the first and second pins 4 and 5 of the first row control and the first column control pin 6, and if the first column control key 16 is closed before the first row control key 15, the power supply to the windings 12-2 of the alternating relay floor in the first column and on the relay element 1 does not arrive, since the second contact is open the common contact 5 controls the first row. After the key 15 is closed, the first line is powered by the winding 12-2 of the polarized disconnecting relays of the first line: bus 3 - switching and opening contact of the contact group 3 - winding 12-2 of the first line - diodes 9 of the third group - contact 5 - bus 14, windings 12-2 disconnecting polarized relays of the first column along the following chains: women 13 - switching and disconnecting contacts of the contact group 3 - windings 12-2 of the first column1, and - diodes 8 of the second group - contact 6 - diodes 1 1 penta groups - pin 5 - bus 14, and winding 2 relays of element 1 o not and Shih (a 13 - 10 -.diod winding 2 of the fourth group - track 6 l

Then the Mejies time interval, defined by ycTauKoii of the relay element 1, fails to respond, with the help of contact pins 3, size n: there are switching and disconnecting contacts and locking a1C1Ts relocation and locking of the 1И11 contact ,, it receives a 1I1IiIyo switch about the relocation and relocation relay, located at the intersection of the first row and column, by penalty: bus 13 - switching and locking contact group contacts 3 - contact 4 - winding 12-1 - diode 7 of the first group - contact 6 - diode of the 11th group. 1 - K0} 1 tick 5 - tire 1A. The relay operates on the winding 12-1 turn on.

When the control keys 15 and 16 are opened, the first row and column open contacts 4-6. In this case, the winding 2 of the relay element 1, which turns off, loses power, and its switching contact group 3 returns to its initial position. The switched on relay will not change its state, i.e. will save information.

The inclusion of {polarized relays located at the intersection of other rows and columns is carried out in the same way by closing the keys 15 and 16 of controlling the corresponding rows and columns.

Thus, the proposed technical rectification allows to increase the operational reliability of the matrix switch, since it ensures the continuity of the power supply of the relay element as well as due to the absence of second control contacts in each column.
