Abstract

종래 보다도 얇은 누름버튼 스위치의 실현이 가능하면서 긴 키 압하 스트로크가 얻어짐과 동시에, 누름버튼 스위치의 박형화에 수반하는 오퍼레이터가 받는 위화감이나 장해의 발생을 방지하고, 쾌적한 박형의 키보드를 싼 값으로 실현하는 것이 가능한 누름버튼 스위치를 제공한다.A thinner push button switch can be realized than conventionally, and a long key pressing stroke can be obtained, while preventing the occurrence of discomfort and obstacles caused by the thinning of the push button switch, and providing a comfortable thin keyboard at a low price. Provides a pushbutton switch that can be

가이드 통(2a)과 스템(6a)의 사이에, 이들 가이드 통(2a)과 스템(6a)에 대해서 각각 슬라이딩 가능하게 키레버(5)를 형성하고, 이 키레버(5)를 통하여 압하되면 복귀가능하게 반전동작되어서 스템(6a)의 이동방향에 있어서의 실효 길이가 줄어듬과 동시에, 이반전에서 접점과 전환을 행하는 접점 압하부(8c)를 일부에 갖는 컵고무(8)를, 키레버(5)를 통하여 복귀용 코일 스프링(7)과 직렬로 설치하였다.Between the guide cylinder 2a and the stem 6a, the key lever 5 is formed so that sliding is possible with respect to these guide cylinder 2a and the stem 6a, respectively, and when it is pressed down through this key lever 5, The key rubber is provided with a cup rubber 8 having a part of the contact pressing portion 8c which switches over with the contact in reverse operation while reducing the effective length in the moving direction of the stem 6a by reversibly inverting. (5) was installed in series with the return coil spring (7).
