Abstract

Изобретение относитс к электротехнике и может быть использовано в электронно-счетных машинах. Цель изобретени - упрощение конструкции. Коммутирующее устройство содержит упругую крышку 1, клавишу 2 и упругую плату с проводниками. Клавиша прижимаетс к крышке пружиной, котора также центрирует клавишу после сн ти усили и выполн ет функцию токопровод щего элемента. Плата 9 выполнена с изол ционными выступами 10, а верхн часть клавиши имеет дугообразное сужение ребер и боковых стенок. В качестве подвижных контактов использованы дугообразные выступы на внутренней поверхности клавиши. Клавиша совершает качательное движение в нескольких плоскост х дл обеспечени выборочного срабатывани контактов. В момент замыкани клавиша 2 взаимодействует с выступами 10, деформиру при этом корпус 1 и плату 9. 1 з.п. ф-лы, 4 ил.The invention relates to electrical engineering and can be used in electronic counting machines. The purpose of the invention is to simplify the design. The switching device contains an elastic cover 1, a key 2 and an elastic board with conductors. The key is pressed against the cap by a spring, which also centers the key after the force is removed and acts as a conductive element. The board 9 is made with insulating protrusions 10, and the upper part of the key has an arcuate narrowing of the ribs and side walls. Arc-shaped protrusions on the inner surface of the key are used as moving contacts. The key rotates in several planes to provide selective triggering of the contacts. At the time of closing the key 2 interacts with the protrusions 10, thus deforming the body 1 and the board 9. 1 CW f-ly, 4 ill.

Claims

Claim

1. A switching device comprising a case with windows, under the keys, a board with conductors and movable contacts, each key having side walls with arched ribs that are directed to its central part, spring-loaded with a conductive spring and installed to interact with the inner surface of the case in its working position and swing in several planes to ensure selective actuation of the movable contacts with the conductors. boards, characterized in that, in order to simplify, the housing is made elastic, the board carrying the conductors is made of elastic material with insulating arcuate protrusions, and the key is with protrusions that are sprayed with a conductive layer and act as movable contacts, while the key is installed with the possibility of interaction with the insulating protrusions of the board in operating positions.

2. Device pop. 1, characterized in that the side walls of the key are also directed towards its central part.
