Extra characters may occur when a high velocity or heavy bottoming force is applied to a keybutton of a capacitive keyboard. This force is transmitted by the frame 10 in area 11 to the tip of pivot plate 12 which is adjacent the button struck. This causes the pivot plate 12 of the unwanted key position to move downwardly, causing an unwanted character followed by the desired character. This failure always occurs with the pivot plate 12 directly behind the button which is depressed with excess force.
