Description
Изобретение относитс к электротехнике , а именно к коммутационной техника, и может быть использовано в различных радиотехнических устройствах и аппаратуре св зи, в частности в качестве переключателей в телефонных аппаратах и кнопочных панел х номеронабирателей в устройствах в программированным набором номеров.The invention relates to electrical engineering, in particular to a switching technician, and can be used in various radio engineering devices and communications equipment, in particular, as switches in telephone sets and keypads of dialers in devices in a programmed dialing of numbers.
Известен клавишный переключатель, содержащий печатную плату, контакт в виде мембраны, изол ционное основание , гибкую пластину и кнопкуj установленную в отверстии кожуха. Контакт закреплен между изол ционным основанием и платой и может замлкать контактные дорожки на ней при нажатии на кнопку, при этом эластична пластина прогибаетс и при отпускании возвращает кнопку в первоначальное положение 1. .A key switch is known, comprising a printed circuit board, a membrane-shaped contact, an insulating base, a flexible plate and a button j installed in a hole in the casing. The contact is fixed between the insulation base and the board and may short the contact tracks on it when the button is pressed, the elastic plate bends and returns the button to its original position when released.
Недостатком данного переключател вл етс ограниченность его применени , так как он может осуществл ть только замыкание контактов и не обеспечивает их переключени .The disadvantage of this switch is its limited use, since it can only make contact closure and does not provide for switching.
Известен также клавиатурный телефонный номеронабиратель, содержащий упругую мембрану из пластичного материала , на который установлены кнопочные переключатели. Под каждой кнопкой имеетс электропроводный участок мембраны, который замыкает печатные проводники на плате при нажатии на кнопку .Also known keyboard telephone dialer containing an elastic membrane of plastic material, on which the pushbutton switches are installed. Under each button there is an electrically conductive membrane section that closes the printed conductors on the board when the button is pressed.
Конструкци указанного номеронабирател проста, но также не обеспечивает переключени контактов.The design of the indicated dialer is simple, but also does not provide for switching contacts.
Наиболее близким к предлагаемо Closest to the proposed
10 по технической сущности вл етс коммутирующее устройство, содержащее печатную плату и установленную на ней диафрагму, выполненную трапецеидальной формы в осевом сечении. На верши15 не диафрагмы со стороны платы установлен контакт. При нажатии на диафрагму контакт замыкает дорожки на кон тактной плате 3.10, by its technical nature, is a switching device comprising a printed circuit board and a diaphragm mounted thereon, made of trapezoidal shape in axial section. At the top of the non-diaphragm side of the board contact is made. By pressing the aperture, the contact closes the tracks on the contact board 3.
Основным недостатком известного The main disadvantage of the famous
20 устройства вл етс ограниченность его применени , так как конструкци не обеспечивает переключени контактов .20 of the device is the limitation of its application, since the design does not provide for switching contacts.
Цель изобретени - расширение 25 функциональных возможностей коммутирующего устройства.The purpose of the invention is to expand the 25 functionality of the switching device.
Указанна цель достигаетс тем, что коммутирующее устройство, содержащее печатную плату с контактными This goal is achieved by the fact that a switching device containing a printed circuit board with contact
