ABSTRACT:
A keyboard has a single row of eight multi-position keys with the letters arranged in a standard QWERTY keyboard configuration. The eight keys correspond to the eight fingers used when touch typing; each finger operates one key, and that key contains all the letters that the finger normally accesses when touch typing on a standard QWERTY keyboard. With this design, no finger has to move to a different key while typing. When depressed at different locations on its key face, each key either moves straight down, or down while tilting slightly about one of a plurality of axes. Three-position keys have two tilt axes and six-position keys have five tilt axes. The switches utilize contacts located on the bottom of the switches which may be conductive or nonconductive.
