Claims

[Claims for Utility Model Registration] A movable electrode formed of a conductive material and provided on the entire one side of a first insulating sheet that is displaced by external stress; A spacer molded from the material and this spacer. In the Kerat keyboard switch, the second insulating sheet is composed of a fixed electrode made of a resistive material and in close contact with the other surface of the keyboard, and a reinforcing plate that abuts on a second insulating sheet provided with the fixed electrode on the entire one side. 1. A flat keyboard switch characterized in that a plurality of elastic bodies are arranged regularly over either a surface of a reinforcing plate contacting side of a flexible sheet or a surface of a reinforcing plate opposite to this surface.
