The blocking contact 20 of the magnetic starter and the closing contact 21 of the control button 10. Parallel to the serially connected closing contact 19 of the first intermediate relay and the closing block contact 20 of the magnetic starter are connected in series the disconnecting contact 22 of the first intermediate relay and the disconnecting block contact 23 of the magnetic starter and connected in series with the disconnecting block contact 23 of the magnetic starter and closing contact 21 button 10 control is connected to the closing contact 24 of the second intermediate relay.

The device works as follows.

When the supply voltage is applied to pins 1 and 6 for connection to a power source, the device is in the first stable (initial) state — the devices are disconnected.

When the control button 10 is pressed for the first time, its contacts 8 and 9 are closed and contacts 14 and 21 are closed, the winding of the coil 4 of the second intermediate relay is energized via a circuit pin 6 - pin 21 - auxiliary contact 23 - pin 22 - a coil winding 4 - pin 1 and the winding of the buzzer of the buzzer 5 is triggered by the drive 6 - pin 21 - auxiliary contact 23 - pin 22 - contact 18 - the winding of the coil 5 - pin 1. The buzzer sounds, the second intermediate relay is activated, its contact 12 is closed and the contacts 7 are closed, 15 and. 24, a circuit is prepared for energizing the magnetic starter.

When the control button 10 is released for the first time, its contacts 14 and 21 are opened and contacts 8 and 9 are closed, the coil 2 of the magnetic actuator is energized through the circuit pin 6 - parallel connected pins 9 and 11 - pin 8 - pin 7 - coil winding 2 - pin 1. The power supply of the coil 4 winding of the second intermediate relay is carried out via the circuit terminal 6 - contact 24 - contact 22 - the winding of the coil 4 - terminal 1, and the power of the acoustic alarm 5 - via the circuit terminal 6 - contact 24 - contact 22 - contact 18 - alarm 5 - pin 1. Magnetic starter is triggered, opens its auxiliary contact

23 and the block contacts 13, 16 and 20 are closed, the starter becomes self-blocking, and the coil 3 winding of the first intermediate relay is energized via a circuit pin 6 - block pin 16 - pin 15 - coil coil 3 - pin 1.

The first intermediate relay is activated, its contacts 11, 18 and 22 open, and contacts 17 and 19 close. The coil 4 winding of the second intermediate relay and the buzzer 5 lose power, the acoustic signal and the second intermediate relay go off, contacts 7 open.

15 and 24 and the contact is closed. The winding of the coil 3 of the first intermediate relay loses power, the relay switches off, its contacts open 17

and 19 and contacts 11, 18, and 22 are closed. The device switches to the second steady state — the magnetic starter is activated through the circuit; terminal 6 — parallel-connected contacts 9, 11, and 12 — the auxiliary contact 3 — the coil winding 2 — the output 1,

When the control button 10 is pressed a second time, its contacts 8 and 9 open and contacts 14 and 21 close, coil winding 3 of the first intermediate relay of the circuit, output 6, block contact 16, contact 14, coil winding 3, output 1 are energized.

The first intermediate relay is activated, its contacts 11, 18 and 22 are opened and the contacts 17 and 19 are closed. The coil 4 winding of the second intermediate circuit is energized via pin 6 - pin 21 - contact terminal 20 - pin 19 - coil winding 4 - pin 1 ( the buzzer 5 is not activated, since contact 18 is open. The second intermediate relay is triggered, its contact 12 is opened and contacts 7, 15 and 24 are closed and the coil 3 winding of the first intermediate relay is energized through a circuit pin 6 - parallel-connected block contact

16 and pin 17 — parallel contacts 14 and 15 — winding of coil 3 — pin 1.

The coil 2 of the magnetic starter loses power, the starter turns off, its block contacts 13, 16 and 20 open and the block contact 23 closes, and the power of the coil 3 winding of the first intermediate relay

pin 6 - pin 17 - parallel-connected contacts 14 and 15 - coil winding 3 - pin 1, coil 4 winding of the second intermediate relay loses power, the relay is disconnected, its contacts 7, 15 and 24 are closed, and contact 12 is closed, The coil 3 winding of the first intermediate relay is then supplied via the circuit 6 - pin 17 - pin 14 - coil 3 - pin 1.

When the control button 10 is released a second time, its contacts 14 and 21 open, and contacts 8 and 9 close. The coil 3 winding of the first intermediate relay loses power, the relay turns off, its contacts 17 and 19 open, and contacts 11, 18 and 22 close. the first stable (initial) state, the devices are disconnected.

Thus, in the initial state, all devices of the device are turned off, with odd presses on the control button, a warning signal is given, with odd releases of the control button, the magnetic starter is turned on (other devices are turned off), and with even presses and releases of the control button the magnetic starter is switched off without giving a warning signal.

Such a solution saves electrical energy, since in the current mode, when the voltage is applied (before turning on the magnetic starter), the device is turned off and does not consume energy, and in the operating mode only the magnetic starter is turned on, and the other devices are turned off.

In addition, the reliability of the device is improved by providing alternate switching of contacts, i.e. some contacts are triggered after triggered

others, since the apparatuses are turned on and off one after another in succession.
