Abstract

The purpose of this invention is to provide a pushbutton switch and a keyboard using the same with excellent operation touch without inhibiting the tongue movement. The pushbutton switch (1) of this invention is provided with: a stationary contact member (21); and a flat spring member (10) configured also as a movable contact member (15) for the contact and separation with respect to the stationary contact member (21), having a dome (10a) allowing the press operation and protruded as a dome shape, and being capable of performing reverse rotation of the dome (10a); the flat spring member (10) has a tongue (10f) protruded inward from the proximity of the top of the dome (10a), and the pressed region (PR) of the flat spring member (10) is an annular portion larger than the tongue (10f) from the top view.

Description

technical field [0001] The present invention relates to a key switch that performs electrical contact separation with the inversion of a dome portion and a keyboard using the key switch. Background technique [0002] In switchgears used in electrical equipment, pushbutton switches are required to perform reliable switching operations and have clear operating tactile sensations. For example, Patent Document 1 discloses a switch device in which an electrical switching operation is performed by pressing a movable contact member so that the movable contact member comes into contact with a fixed contact portion, and the movable contact member performs an inversion operation. And produce operation touch. [0003] Figure 35 It is a schematic sectional view showing the structure of the switch device 100 of patent document 1. Figure 36 It is a schematic diagram showing the outline of the movable contact member 101 . Figure 37 It is a plan view showing a modified example of the ...
