Claims

[Scope of Claim for Utility Model Registration] (1) Each spacer in a keyboard switch has a click metal plate that reverses and returns in response to the application and release of operating force to sense the opening and closing operations of the switch. In a click-type keyboard switch configured to be placed in a through hole, a sheet-shaped section is provided on the top of the insulating sheet placed on the spacer for concentrating the operating force on the top area of the click metal plate. A click-type keyboard switch characterized in that it is configured to be equipped with (2) The click-type keyboard switch according to claim 1, wherein the sheet-like section is constructed by punching out a sheet-like member into a desired shape through a continuous portion. (3) Claim characterized in that the sheet-like section is formed by two thin sheet-like members, and the two sheet-like members are joined so that their respective continuous portions do not overlap. Click-type keyboard switch described in (2).
