Description

15А) КОММУТАТОР15A) SWITCH

II

Изобретение относитс к области автоматики и коммутационной техники .The invention relates to the field of automation and switching technology.

Известны коммутаторы, содержащие источник питани , многопозиционный переключатель и ключевые элементы.Switches are known that contain a power source, a multi-position switch and key elements.

Наиболее близким к изобретению вл етс коммутатор, содержащий источник питани и многопозиционный переключатель, подвижный контакт которого через общий резистор соединен с общей шиной, а также в каждом канале, ключевой элемент .Closest to the invention is a switch comprising a power source and a multi-position switch, the movable contact of which through a common resistor is connected to the common bus, and also in each channel, a key element.

Недостаток известных устройствнизкое быстродействие.A lack of known devices is low speed.

Цель изобретени - повышение быстродействи коммутатора.The purpose of the invention is to increase the speed of the switch.

Поставленна цель достигаетс тем, что в коммутатор, содержащий источник питани и многопозиционный переключатель, подвижный контакт которого через общий резистор соединен с общей шиной, а .также в каждом канале ключевой элемент, введеныThe goal is achieved by the fact that a switch containing a power source and a multi-position switch, the movable contact of which through a common resistor is connected to a common bus, and also a key element in each channel,

Claims

The switch contains a power supply 1, a multi-position switch 2, the movable contact of which is connected to a common bus C through a common resistor 3, one output of power supply 1 1 is connected to a common bus C, and the other output is connected to the first terminals of the channel resistors 5, the second output of each of which connected to the same fixed contact multi-position switch 2, the movable contact of which is connected to the inputs of the Comparators 6, in each channel the output of the comparator 6 is directly connected to the first input element And 7 and black NOT element 8 - with a second input of AND elemeita previous channel 7, and the output of AND gate 7 to the sound control prdklyuchen yuschemu L key entry component 9 the channel. The switch works as follows. The voltage of the power supply source 1 is supplied to the voltage divider, which is made on the resistors 5, the multi-position switch 2 and the resistor 3. 3 will increase discretely, causing the comparators to operate alternately. 6 When the multi-position switch 2 is closed to the first resistor 5, the comparator 6 of the first channel is triggered, the unitary logic level from whose output On element 7 to another input from which the output of element 8 on the second channel also serves a single logical level. At the output of the element And 7, the first channel forms a single logic level and. the corresponding key element 9 opens. When the multi-position switch 2 is closed to the second resistor 5, a single logic level is formed at the outputs of the first and second channels Comparators 6. From the output of the comparator 6 of the second channel, the unit logic level is inverted through the And channel element 7 of the previous channel. At the same time, unit logic levels from the output of comparator 6 of the second channel and HE element 8 of the third channel are fed to the inputs of the And 7 element of the second channel. B, as a result of this, at the output of the element And 7 a single logical level is formed, which opens the key element 9 of the second channel. Further operation of the switch is similar. Thus, the introduction of channel resistors and in each channel of the comparator and the elements And and did not allow to increase the speed of the proposed switch in comparison with the known. Claims of the invention A switch containing a power source and a multi-position switch, the movable contact of which is connected to a common bus through a common resistor, as well as a key element in each channel, characterized in that channel resistors are introduced in each channel and the comparator and elements in each channel Both and NOT, with one output of the power supply connected to the common bus, and the other output connected to the first terminals of the channel resistors, the second output of each of which is connected to the same fixed terminal the act of a multi-position switch, the movable contact of which is connected to the inputs of the comparators, in each channel the output of the comparator is directly connected to the first input of the element AND through the element NOT to the second input of the element AND of the previous channel, and the output of the element AND is connected to the control input of the key element this channel.
