To the first pole of the power source 1 through the first fuse 6, the winding of the first fire relay 8, the front contact of the first signal relay 12, the first line wire 24 is connected to the first output of the first winding of the first signal transformer 4, to the second output of which is connected the first output of the first winding of the second signal transformer 5, and through the second line wire 25 - the second pole of the power source 2, the first leads of the first and second windings of the control transformer 3, the first lead of the first diode 22, the first lead the windings of the control relay 11, to the second terminal of the first winding of the second signal transformer 5 through the third line wire 26 and the front contact of the first tee of the second signal relay 13, the first terminal of the winding of the second fire relay 9 is connected, to the second terminal of which is connected the first terminal of the second fuse 7, the second terminal which is connected to the first pole of the power source 1, to which the second terminal of the first winding of the control transformer 3 is also connected, to the second terminal of the second winding of this transformer the first output of the control relay 10 winding is connected, to the second output of which the common contacts of the first and second tees of the first 15 and second 16 fire relays are connected through the front contact of the second tee of the second signal relay 14, to the rear contacts of which the third output of the first winding is connected through the fourth line wire 27 the control relay and through the front contact of the first tee of the control relay 17 - the second output of the first rectifier 22, the second and fourth outputs of the second winding of the control relay 11 are connected to the first and the second terminals of the second rectifier 23, respectively, the first terminal of the second winding of the first signal transformer 4 through the front contact of the second tee of the control relay 18 is connected to the terminal of the main thread of the first yellow lamp 20, to the common terminal of which is connected the second terminal of the second winding of the first signal transformer 4, the output the backup thread of the first yellow lamp 20 is connected to the rear contact of the second tee of the control relay 18, the first output of the second winding of the second signal transformer 5 through the front oic third contact tee of the control relay 19 is connected to the second terminal warp yarn yellow light bulb 21, a common terminal which is coupled the second terminal of the second winding of the second signal transformer 5, the output of the spare second filament lamp yellow light is coupled to the rear terminal of the third Tee control relay 19.

The action of the circuit is as follows. With the excitation of the first and second signal relays by the contacts of their tees 12 and 13, the power circuits of the first and second signal transformers 4 and 5 are created, through which the first and second yellow lights 20, 21 are turned on. The integrity of the power circuits, incl. and the filaments of yellow fire lamps is controlled by fire relays 8 and 9. When the linear wires are closed, the first 6 or second 7 fuses blow, which is also controlled by fire relays. Through the winding of the control relay 10 through the fourth line wire 27 from the control transformer 3, power is supplied to the control relay 11. When the traffic light is forbidden (signal relays are de-energized), the first fire relay 8 is activated with integrity monitoring of the main red light thread (not shown) through the front contact of the tee the first fire relay 15 and the rear contact of the second tee of the second signal relay 14 creates a chain of the first winding of the control relay 11. This relay is connected to the second winding The diode 23 is excited by shunting the first winding with the first diode 22 by contacting the first tee of the control relay 17. The resistance of the first winding of the control relay 10 (NMSh-40) is many times less than the resistance of the winding of the control relay 11 (NMSh-7000). The control relay 11 is first excited by the second diode 23, and with the contact of the first tee connecting the control relay 17 of the first diode 22, the control relay 10 is also excited. The control 10 and control 11 relays can be excited when two yellow lights are lit. These lamps can be checked for integrity (front contacts tees of the first 15 and second 16 fire relays close the circuit, and the contact of the second tee of the second signal relay opens).

When one of the yellow fire lamps 20 or 21 burns out, the circuit of the fire relay 8 or 9, respectively, breaks, the tees of the first 15 and second 16 of these relays breaks the power supply circuit of control 10 and control 11 of the relay. The control relay 11 with its contacts of the second 18 and third 19 tees switches the yellow light signal lamps 20 and 21 to the backup threads.

The implementation of the proposed device provides significant savings in cable cores both in new construction and in the reconstruction of the station.
