There are only the fourth 1.4 and fifth 1.5 (the number of closing 2 and opening 3 contacts of each relay of the first switch depends on the combination of their switching). The second switch 4 consists of four relays 4.1-4.4, respectively, with closing contacts 5.1 (5.1, - 5.4), 5.2 (5.2, -5.24), 5.3 (5.3, - 5.3E), 5.4 (5.4, - 5.44) and opening contacts 6.1 -6.4 (the number of closing contacts 5 for each relay of the second switch depends on the embodiment of the distributor according to the schemes shown in Fig. 2).

One output winding of each odd (even) switched on relay of the first switch 1 is connected to the nep (second) clock bus 9 through a series connected corresponding decoupling diode 15 to the right On, the closing contact 2 of the previous even (odd) switched on relay of the first switch 1 and the closing contact 5 of the corresponding relay of the second switch 4 V shown in FIG. 2 of the embodiment of the distribution of the connection of the windings of the relay of the first switch 1 is made according to the connection diagram shown in FIG. 1. In the first switch-on combination, implemented by the relay 4.1 of the second switch 4, the first 1.1 and fifth 1.5 are odd, and the second switch 1.2 of the first switch 1 is even, the first 1.1 and the second 1.2 relays are previous respectively for the second is 1.2 and the fifth 1.5 relay Accordingly, in the embodiment shown in FIG. 2, the winding of the first (odd) switched on relay 1.1, is connected to the first clock bus 9 through a series-connected decoupling diode 15.1 and the closing contact 5.14 of the first relay 4.1 of the second switch 4 (the previous relay is not present), the winding of the second (even) turned on relay 1.2 is connected to the second clock bus 10 through a serially connected decoupling diode 15.2, the closing contact 2.12 of the previous odd (in this case, the first 1.1) switch-on relay of the first switch 1 and the closing contact 5.13 of the first relay 4.1 of the second switch 4, the winding of the fifth (odd) switched on relay 1.5 is connected to the first clock bus 9.

For the quick disconnection of the included relays, the distributor may contain a 20 Stop button connected to the power bus 17.

Relay distributor works as follows.

Before starting the relay distributor, select the required combination of the connection sequence of the relay of the first switch 1 by applying a signal to one of the input buses 19.1-19.4 of the second switch 4. So, for example, when the signal is fed to the input bus 19.1, the relay start sequence of the first switch 1 will correspond to the first the combination shown in FIG. one.

When you press the 16 Start button, the auxiliary winding51 will receive power.

relay 11 via the circuit: bus 17 - buttons 20, 16 - contacts 6.1 (3.5), 6.2 (3.4), 6.3 (3.52), 6.4 (3.53) - winding 11 - bus 18. Auxiliary relay 11 will work and close its contacts 12 , 13.

Contact 13 bypasses the start button 16, which can be released, and contact 12 will apply the winding of the first relay 4.1 of the second switch 4 through the circuit: input 19.1 - winding 4.1 - contact 12 - bus 18. Relay 4.1 will operate, open its contact 6.1 and close the contacts 5.1, -5.C (in this case, the windings of the relay 1.1 and 1.5 of the first switch 1 will not receive power, since there is no voltage on the first clock bus 9, and the winding of relay 1.2 will not receive power, since contact 2.1 is open). The clock generator 7 will receive power along the circuit: bus 17 - button 20 - contact 5.1 - generator 7 - bus 18. Clock generator 7, which can be a relay-pulse-pair, will operate and switch its output contacts 8 In this case, the power is removed from the second clock bus 10 and goes to the first bus 9. The winding of the first relay 1.1 of the first switch 1 along the circuit receives: bus 17 - button 20 - contact 8 - bus 9 - contact 5.17- diode 15.1 - winding 1.1 - bus 18 (relay winding 1.5 will not receive power, since contact 2.23 is open.

Relay 1.1 will work, will close its contacts 2.1., - 2.1-, and will turn on self-blocking (in this case, the winding of relay 1.2 will not receive power, since there is no voltage on the second clock bus 10). At the end of the clock pulse (the duration of which must be longer than the response time of any relay of the first switch 1, and if the relay turns on any drive or mechanism, then the total time for activating the relay and starting the drive or mechanism), output contact 8 will return to the initial state. In this case, the power is removed from the first clock bus 9 and goes to the second bus 10. The winding of the second relay 1.2 of the first switch 1 will receive power through the circuit: bus 17 - button 20 - contact 8 - bus 10 - contacts 5.13, 2. diode 15.2 - winding 1.2 - bus 18. Relay L2 will work, will close its contacts

2.2, -2.23, ь will become on self-blocking (in this case, the winding of the relay 1.5 will not receive power, since there is no voltage on the first clock 9). At the end of the clock pulse, output contact 8 is switched again. In this case, the power is removed from the second clock bus 10 and fed to the first

JQ bus 9. The winding of the first relay 1.5 of the first switch 1 will be supplied: bus 17 - button 20 - pin 8 - pin 9 - contacts 5.4 ,,, 2.23 - diode 15.5 - winding 1.5 - bus 18. Relay

1.5 1.5 will work, open its contacts 3.5., - 3.5-j, close contact 2.5 and turn on self-blocking. In this case, the winding of the auxiliary relay 11 loses power (since the

20 pins 6.1 and 3.5,), however, the relay will not turn off, but will be held in the actuated state for a time depending on the capacitance of the capacitor 14, which is selected so that the 1.5 relay turns on self-blocking (i.e. 2.5 closed before the start of contact 12 of the auxiliary relay 11). At the end of the delay time

30 auxiliary relay 11 is turned off and opens its contacts 12, 13. In this case, the winding of the first relay 4.1 of the second switch 4 loses power, which, having turned off, will open its contacts 5.1, -5.14 and close contact 6.1. The power is lost and the clock generator 7 is turned off, and its output contact 8 will return to its original position.

40 In this state, the distributor can be indefinitely long.

The dispenser is turned off by pressing the 20 Stop button. This will lose the power of the winding

45 switched on relays 1.1, 1.2, 1.5, which are turned off, and the distributor will return to the initial state.

The activation of the relay in any other combination is similar.

50 by sending a signal to the corresponding input bus 19 of the second switch 4.

Thus, the proposed solution allows to significantly expand

55 functionality of the relay distributor, since it is possible to turn on any number of relays in any combinations and in any sequence, i.e. distributed spruce maybe

widely used in various devices switching electrical circuits.
