Abstract

Laminar conical spring to be used as recovery spring or diaphragm of a key for a keypad. The conical laminar spring D according to the present invention is formed with spiral undulations P in a peripheral zone around its central circular part 10. Each one of the spirals extends from a specific point of the perimeter of the circular part 10. The spirals P can extend from a minimum of two points on the perimeter of the circular part which are separated from one another, at identical intervals, and are preferably to be extended from an uneven number of said points. If the laminar conical disc D according to the present invention is applied to the diaphragm it will deform uniformly with respect to the circumferential direction. When deformation takes place, the force acts uniformly and the direction of functioning is uniform.
