ABSTRACT:
A key switch cap mounting arrangement for use on a keyboard is disclosed in which the key cap and a column on which it is supported are formed with a cylindrical post and mating socket aligned with axes angularly offset from an axis perpendicular to the upper surface of the key cap and the longitudinal axis of the column. The cap and column can be assembled either so that the surface of the key cap is perpendicular to the axis of the column to provide for a sloped keyboard, or so that the surface of the cap is tilted from its perpendicular position to provide for a stepped keyboard.
