Description
Изобретение относитс к электротехнике, в частности к коммутационным устройствам.The invention relates to electrical engineering, in particular to switching devices.
Цель изобретени - расширение коммутационных возможностей.The purpose of the invention is the expansion of switching capabilities.
На фиг. 1 изображено коммутационное устройство В исходном состо нии/ нродоль- ный разрез; на фиг. 2 - упруга мембрана вид сверху; на фиг. 3 - устройство с видом на печатную плату, разрез.FIG. 1 shows the switching device in the initial state / near-length section; in fig. 2 - elastic membrane top view; in fig. 3 - device with a view of the PCB, a slit.
Устройство состоит из мембраны 1, выполненной из эластичного полупрозрачного изол ционного материала (например, полиуретана) и покрытого с наружной стороны тонким- слоем 2, выполненного из электропровод щего и непрозрачного маПри монтаже источник 9 видимого излучени сначала устанавливаетс на печатную плату 5 так, что он не выступает над платой 5. При дальнейшей сборке соедин ют печатную плату 5 с контактами 7 и мембрану с контактами 3. Последние за счет упругих свойств изгибаютс и вход т между выступами 13 контактов 7. После этого источник 9 видимого излучени с незначительной деформацией выводов вводитс 0 между контактами 3.The device consists of a membrane 1 made of elastic translucent insulating material (e.g. polyurethane) and coated on the outside with a thin layer 2 made of electrically conductive and opaque mapper. When mounted, the source of visible radiation 9 is first installed on the printed circuit board 5 so that does not protrude above board 5. During further assembly, a printed circuit board 5 is connected to contacts 7 and a membrane with contacts 3. The latter, due to elastic properties, bend and enter between projections 13 of contacts 7. After this, the source 9 hic visible radiation with little deformation pin is inserted between the contacts 3 0.
При нажатии на мембрану 1 упругие подвижные контакты 3 перемещаютс и размыкают пары дополнительных неподвижных контактов 7, а затем замыкают неподвижтериала , подвижных контактов 3, выпол- ные контакты 6. При сн тии усили опененных из упругого токопровод щего мате риала, металлической токопроводинхей пластины 4 с отверсти ми, печатной платы 5 с неподвижными контактами 6. На печатной плате 5 установлены также пары дополнительных неподвижных контактов 7 20 с изол ционными втулками 8 и источник 9 видимого излучени , например светодиод.When pressing the membrane 1, the elastic moving contacts 3 move and open a pair of additional stationary contacts 7, and then close the stationary material, moving contacts 3, the contacts 6 made. When the force is removed from the elastic current-carrying material, the metal current-carrying plate 4 s openings of the printed circuit board 5 with fixed contacts 6. On the printed circuit board 5 there are also installed pairs of additional fixed contacts 7-20 with insulating sleeves 8 and a source of 9 visible radiation, for example, a LED.
ратора коммутационное устройство возвращаетс в исходное состо ние.The switching device returns to its original state.
