Abstract
An electronic computer keyboard is constructed to provide the minimum keystroke resistance sufficient to prevent accidental switch closures otherwise resulting from the weight of the operator's fingers resting on the keys. This forces the operator to move his or her hands over the keyboard with locked wrists. It also eliminates the need of the operator to hold his or her hands up to prevent inadvertent key depressions thereby reducing stress and fatigue on the operator's shoulders, forearms, wrists and hands.
