Изобретение относитс к электротехнике , в частности к коммутационным устройствам.The invention relates to electrical engineering, in particular to switching devices.
Целью изобретени вл етс улучшение удобства в эксплуатации.The aim of the invention is to improve usability.
На фиг, 1 изображено устройство, общий вид; на фиг, 2 - контактна пружина.Fig, 1 shows the device, a general view; FIG. 2 is a contact spring.
На плате 1 с кольцевым контактом 2 расположена крестообразна пружина 3 с лапками 4 и дугообразным выступом 5, направленным в сторону центрального контакта 6, цветной экран 7 и пластина 8 свободно расположены в окне рамы 9 и закрыты упругой прозрачной пленк ой 10,On the board 1 with the annular contact 2 there is a cross-shaped spring 3 with the tabs 4 and the arcuate protrusion 5 directed towards the central contact 6, the color screen 7 and the plate 8 are freely located in the window of the frame 9 and covered with an elastic transparent film 10,
На упругой прозрачной пленке 10 отсутствует печать, рама 9 требуемого цвета акцентирует внимание на белой пластине 8 со щелевым отверстием 11, Опорные лапки 4 имеют скруглени в месте контактировани с кольцевым контактом 2,On the elastic transparent film 10 there is no seal, the frame 9 of the desired color emphasizes the white plate 8 with a slit hole 11, the supporting legs 4 have rounding at the point of contact with the ring contact 2,
Пластина 8 установлена между экра- 25 ном 7 и пленкой 10 и может работать под разными углами к плоскости платы 1 в зависимости от постановки пальца при незначительном ходе нажати The plate 8 is installed between the screen 25 and the film 10 and can work at different angles to the plane of the board 1 depending on the position of the finger with a slight stroke
Устройство работает следующим обазом .The device works as follows.
При нажатии на пластину 8 пленка 10 прогибаетс , экран 7 копирует поожение пластины 8 и воздействует а горизонтальную площадку пружины 3, ри этом лапки 4 расход тс (изгибатс ) пока выступ 5 не коснетс контакта 6 на плате.When pressing the plate 8, the film 10 bends, the screen 7 copies the position of the plate 8 and acts on the horizontal pad of the spring 3, while the tabs 4 are consumed (curved) until the protrusion 5 touches the contact 6 on the board.

Таким образом электрическа цепь платы 1 замыкаетс через контактную пружину 3, т,е, через цепь: кольцевой контакт 2 - пружина 3 - центральный контакт.Thus, the electrical circuit of the board 1 is closed through the contact spring 3, t, e, through the circuit: ring contact 2 — spring 3 — central contact.
