Thin electrical switch

摘要

An electrical switch which includes a top metal support plate, a triggering member bearing on a bottom of a recess, a bottom metal contact plate having a fixed central contact region, and an adhesive fixing insulating sheet. The adhesive insulating sheet is arranged between a peripheral portion of the bottom face of the top support plate and a peripheral portion of the top face of the bottom contact plate and the adhesive insulating sheet adheres, by its two opposite faces, to each of said two annular portions to form a means for fixing the top support plate to the bottom contact plate.

主权项

1. An electrical switch comprising:
a top support plate produced from a metal plate, the top support plate cut and shaped to delimit a recess having an annular bottom and delimiting an open first central hole; an electrically conducting triggering member having a convex shape and is elastically deformable from a stable rest position in a direction substantially perpendicular to a bottom of the recess, the triggering member comprising a bottom edge positioned to bear vertically downward on a facing top face of the annular bottom; a bottom contact plate produced from a cut metal plate, the bottom contact plate comprising a fixed central contact region arranged facing both the first central hole and a conductive central portion of the bottom face of the triggering member such that, upon deformation of the electrically conducting triggering member, an electric pathway is established between the conductive central portion of the triggering member and the fixed central contact region of the bottom contact plate; and an adhesive fixing insulating sheet comprising a second central hole; wherein the insulating sheet is arranged vertically between a peripheral portion of the bottom face of the top support plate and a peripheral portion of the top face of the bottom contact plate; and wherein the insulating sheet comprises two opposite faces configured to adhere to each of said two peripheral portions to form a means for fixing the top support plate to the bottom contact plate.
