Seamless button

Seamless button, comprising a guiding element (1), a movable actuating element (2) and a switch (3) which is located on a mounting plate (15),

• characterized in that
• the guiding element (1) includes a rigid outer wall (4) that defines an enclosure having an inner chamber (5) with a bottom opening and a top opening, wherein the rigid outer wall (4) is provided, on an outer side in an upper area, with an inwardly offset outer profile edge (4a) and with a pedestal (4b) extending horizontally and forming the transition between the upper outer profile edge (4a) and a remaining part of the outer wall (4);
• the movable actuating element (2) is an elastic button element (2) made of elastic material and provided with a massive middle shaft (8) spaced from inner walls of the chamber (5) by an air gap (5a) and having a planar upper actuating surface (8a) that extends from a first plane that is perpendicular to the upper actuating surface (8a) and that is defined by the upper outer profile edge (4a) of the outer side of one portion of the rigid outer wall (4) to a second plane that is parallel to the first plane and that is defined by the upper outer profile edge (4a) of the outer side of an opposed portion of the rigid outer wall (4), the planar upper actuating surface (8a) having a movement crimp (9) surrounding an outer rim of the actuating surface (8a) above the air gap (5a), wherein the movement crimp (9) is designed in such a way that the elastic material in the area of the movement crimp (9) is relatively thin in a vertical direction and wherein the movement crimp (9) is located directly at an upper rim of the button and enclosing the air gap (5a) located underneath tightly outwardly such that the button is seamless, and with a profile area (10) arranged at an outer circumference of the movement crimp (9) and extending firstly horizontally outwardly and then downwardly and ending in a horizontally outwardly extending protrusion (10a);
• wherein the horizontally outwardly extending portion of the profile area (10) rests on top of the outer wall (4), the downwardly extending portion of the profile area (10) rests on the outside of the outer profile edge (4a) and the protrusion (10a) rests on the pedestal (4b) covering the pedestal (4b) at least partially.
