RELAY SWITCH Russian patent published in 2019 - IPC H01H47/00 

FIELD: astronautics.

SUBSTANCE: invention relates to automation devices and can be used in critical equipment that has increased reliability requirements, for example, in control systems for rocket and space equipment (RSE). Relay switch contains three remote switches with two contact groups, a "-" power bus and four diodes, the first terminals of the on and off windings of the remote switches are combined and connected to the "-" power bus, the second terminal of the turn-on winding of the first remote switch is connected to the main input of turning on the relay switch and the anode of the first diode, the second output of the turn-on winding of the third remote switch is connected to the backup turn-on input of the relay switch and the anode of the second diode, the cathodes of the first and second diodes are combined and connected to the second output of the turn-on winding of the second remote switch, the second output of the switching winding of the first remote switch is connected to the main switching input of the relay switch and to the anode of the third diode, the second output of the switching winding of the third remote switch is connected to the backup turn-off input of the relay switch and to the anode of the fourth diode, the cathodes of the third and fourth diodes are combined and connected to the second output of the switching winding of the second remote switch; conclusions of the closing contact of the first and second contact group of the first remote switch and the output of the closing contact of the first contact group of the third remote switch are combined and are the switched input of the relay switch; outputs of the switching contact of the first contact group of the first and third remote switches, the output of the opening contact of the second contact group of the third remote switch and the output of the closing contact of the first contact group of the second remote switch are combined and are the technological output of the relay switch; switch contacts of the second contact group of the first and third remote switches are combined, the output of the switching contact of the first contact group of the second remote switch is connected to the closing contact of the second switching contact group of the third remote switch and is the output of the relay switch; output of the closing contact of the second contact group of the second remote switch is the telemetric input of the relay switch, and the output of the switching contact is the telemetry output of the relay switch.

EFFECT: technical result is an increase in reliability.
