Abstract:
A device for amplifying movement of an operating button of a switch, said device comprising:a body in which said switch is fixed; a pusher located within said body for translating back and forth along a central longitudinal axis of said body such that a translation of said pusher, with respect to said body, constitutes an amplified motion; a varying-diameter cylindrical member located within said body adjacent to an end of said pusher, wherein said varying-diameter cylindrical member includes: a first support region movable along a ramp of said pusher when said pusher translates back and forth along said central longitudinal axis of said body; a second support region, in permanent contact with a region of said body whatever a position of said pusher; and a third support region in contact with said operating button of said switch; and a single elastic element, wherein said single elastic element is a helical spring which maintains contact of said first support region with said ramp, of said second support region with a region of said body, and of said third support region with said operating button of said switch, said helical spring having a central longitudinal axis which is substantially coincident with said central longitudinal axis of said body, and said helical spring being positioned between said pusher and a flange of said varying-diameter cylindrical members.
