Abstract

A keyboard includes a plurality of keys thereon, each of which is capable of three different switching actions for entry of data or commands into a word processor, typewriter, computer or the like. Each key includes a first inclined surface for generating a first switching action responsive to finger contraction, a second inclined surface for generating a second switching action responsive to finger extension, and a horizontal surface for actuating a third switching action responsive to finger depression. Each key is connected to a respective switch. Each switch includes a carriage operating horizontally against spring-loaded horizontal plugs. The carriage houses a spring-loaded vertical stem attached to the respective key. In one embodiment each key-switch combination is substantially identical to the other. The base is formed into different levels upon which key-switch combinations are mounted.
