Claims

[Scope of utility model registration request]

A movable electrode sheet having a movable electrode consisting of a large number of horizontally striped conductive patterns on a first elastic insulating sheet, and a fixed one consisting of a large number of vertically striped conductive patterns on a second insulating sheet. A flat keyboard switch is provided with a fixed electrode sheet having an electrode, and the movable electrode sheet and the fixed electrode sheet are stacked with a spacer interposed therebetween so that the movable electrode and the fixed electrode face each other with a predetermined gap and intersect with each other. A flat keyboard switch characterized in that the spacer is made of protruding pressure-sensitive conductive rubber disposed either on the movable electrode or on the fixed electrode.
