The invention relates to switching devices of electrical circuits and can be used as a bistable cell (trigger) with indestructible memory of binary counters and other devices of control, monitoring, measurement, and logical units of various branches of engineering.

The purpose of the invention is to increase reliability.

The drawing shows the scheme of the proposed ferride.

The ferride includes a memory element 1, made of retentive material, on which are placed the inclusive 2 and including 3 windings, the ends of which are connected to the negative bus. Between the potios of the memory element 1, a switching A and a closing (switching) 5 hermetic | Us, magnetic core 6 made of a material with high magnetic permeability are installed. The memory element 1 is installed so that its ends are installed 6 foam near the ends of the magnetic circuit 6, on which the demagnetizing 7 and magnetizing 8 opposite windings are placed, the ends of which are connected to the negative thickness. The switching contact-part 9 of the switching-over switch 4 is connected to the start of the switching winding 2 of the memory element 1 and the control pulses input terminal 10, the disconnecting 11 from the beginning of the demagnetizing winding 7 of the magnetic circuit 6, and the closing 12 to the beginning of the turning-on winding 3 the memory element 1 and the magnetizing winding 8 of the magnetic conductor 6. The contact part 13 of the reed switch 5 is connected to the power input terminal 14, a. pin 15 - with output terminal 16. Including 2 and demagnetizing 7 windings are connected in opposite directions.

The operation of the ferride is carried out in the following sequence.

The first control pulse, which is supplied to the input terminal 10, creates, by means of an inclusive winding 2, a flux f of the memory element, which magnetizes it. At the same time, when current flows through the contact parts 9, 1I, a demagnetizing flow 9 is generated by demagnetizing winding 7 of magnetic circuit 6. The flows F and F-2 are equal and flow through the con

tact-details reed switches 4 and 5 counter, so the reed switches do not work. After the end of the pulse, the demagnetizing flux f disappears, and the gyrocals 4 and 5 under the action of the flow, the memory element 1 are activated and remain in the memory mode. In this case, the contact parts 9, 12 and 13, 15 are closed, and the contact parts 9, 11 are opened. The contact parts 13, 15 supply voltage from the input terminal 14 to the output terminal 16. A second control impulse to the input terminal 10, when current flows through the contact parts 9, 12, creates a demagnetizing element 1 through the switching off winding 3 memory At the same time, the magnetizing winding 8 of the magnetic core 6 creates a flux направ directed in accordance with the holding flux and leaving the reed switches 4 and 5 for the duration of the pulse in the actuated state. After the end of the second pulse, the flow disappears, and the reed switches are released, closing contact pin 9, II and opening contact pin 13, 15. The output signal disappears at output terminal 16. With the subsequent arrival of pulses, the cycles of operation of the ferride are repeated.

Thus, for every two input pulses, only one appears at the output terminal 16 of the ferride.

For the device to work, the difference between the flows P and P is not more than the flow of the reed shan of reed switches (f, - Pj: Psrai) or equality of the flows, and F (, Pj) and the increase of the flow P of the flow of the release of reed switches (P + (P)
