<p>A novel actuation mechanism (10) useful, for example, in key switch operation wherein a key stem shaped to mate with apertures in a keyboard (54) arrangement or as individual switches contains oppositely disposed, inwardly deformable, flanged members for captivating the key stem within the key apertures and further includes a torsion spring (32) carried by the key stem and adjustably mounted for rotative movement about a pivot (64) on the key stem. The ends of the torsion spring are movably captivated by the supporting aperture, e.g. keyboard, which in operation provides an excellent resistive tactile feel, and ease of operation on the key release stroke.</p> |
