Description

(54) TWO-POSITION SWITCH

one

The invention relates to electrical engineering, namely to switching technology, and can be used as a two-position switching element with a memory (trigger with a counting start) in automatic devices of various branches of technology.

Known switching switches of electrical circuits with memory, u, containing ferromagnetic cores with control windings and magnetic contacts p.

However, such switches have relatively large dimensions and less tsu.

Known switching switches on gazakona (sealed contacts with memory) f2.

Such switches do not require 20 ferromagnetic cores; however, they are difficult to control, since either two sources of unipolar pulses or one source of bipolar pulses are necessary to control their operation.

Closest to the proposed technical entity is a two-position switch comprising two control hezzacons, release and actuation windings and a diode 3.

However, this switch requires either two sources of unipolar pulses or a single source of bipolar pulses, which makes it difficult to control the switch.

The aim of the invention is to simplify the control of the device by providing the possibility of controlling single-pole pulses from a single source.

This goal is achieved by the fact that one of the contacts of each control gazakon are interconnected and are intended to connect the positive terminal of the input source, the second contact of the first control gazacon is connected to the beginning of the release winding of the specified control gazakon and the beginning of the second control 5 activation winding and the second contact of this control gezacon is connected with the beginning of the release winding of the second control gezacon and through the diode in the forward direction with the beginning of The windings of operation of the first control gezakon, the ends of all the windings are interconnected and are intended to connect the negative terminal of the input source. The drawing shows a diagram of the proposed two-position switch tel. A two-position switch consists of two groups of geza- kons, each of which contains control gezakon 1 and 2 and load gezakon 3 and A, switching loads Рц1 and Кц2. respectively. The first group of gezaquons is set by winding cpa 5 and release 6, which are connected in opposite directions. A second group of hezacones are also seized by actuation windings 7 and release 8, respectively, which are also switched in opposite. One contact of the gezacon 1 and one contact of the gezacon 2 are electrically interconnected and are intended for connecting the positive terminal of the source of the control signal. The second contact of the control gezacon 1 is electrically connected to the start of the release winding 6 of the control gezakon 1 and the beginning of the winding of the actuating 7 of the controlling gezakon 2. the actuation winding 5 of the control gezacon 1. In the actuation winding 5 of the control gezakon 1, a conversion start pulse (INP) is applied through the diode 10. The load gesakons 3 and 4, installed in parallel to the corresponding control gezakonam 1 and 2, commute the loads R | and R | devices. The operation of the device is as follows. Before starting work, a setup pulse is applied to the winding 5 through diode 10, which ensures the actuation of the control gesakons 1 and 2 and the closure of their contacts. When the unipolar control impulses of the first impulse arrive from the source, the latter passes through the closed contacts of the control gazakon 1 into the release winding, beating the actuation coil 1, and the contacts of the gezacons 1 and 3 are released, and the contacts of the gezacons 2 work. Releasing the contacts of the load gazakon 3 provides for the disconnection of the load R, and the actuation of the load of the gazacon k ensures the corresponding inclusion of the load RH. The next impulse through the closed contacts of the control gezakon 2 enters the release coil 8 and through diode 9 into the actuation coil 5- This causes the disconnection of the contacts of the gezakon 2 and and the tripping (shorting) of the contacts of the gezakon 1 and 3. Accordingly, the switching of the Ks and R, 2 . Then the cycle of operation is repeated. Technical and economic effect from the implementation of the invention is. that it allows reducing up to 50% of the hardware costs for controlling the switching of 2 load circuits, since instead of two sources of unipolar pulses or one source of bipolar pulses, only one source of unipolar pulses is required.
