Abstract (en)
[origin: US4580022A] An improved key for typing keyboards or other terminal keyboards, which is substantially larger than the other keys and large compared with the contact to be actuated. In order to avoid tilting during out-of-center pressing, two shears are provided as a guiding means between the mobile and the immobile key parts. The shears are comprised of two frame parts pivoted about axes which are held aligned flush with each other. The shear arms provide four support points at their top free ends which enclose a rectangular surface which is practically congruent with the touch surface.
