Multi direction switch

摘要

A multi direction switch (100) includes a first cover (2), a second cover (3), a printed circuit board (PCB) (4) positioned between the first cover and the second cover, a pair of stacked, orthogonal electrode plates (5) positioned between the second cover and the PCB, a spring member (7) positioned between the first cover and the PCB, and a button (6) for actuating the electrode plates to move on the PCB. The second cover forms a protrusion (21), the button has a radial portion (611) and a wall portion (612) extending downwardly from the radial portion, and the spring member is positioned between the protrusion and the wall portion.

主权项

1. A multi-direction switch comprising:
opposite first and second covers defining a receiving cavity there between; a printed circuit board (PCB), a coil spring member and a pair of intersected electrode plates commonly received in the receiving cavity at different levels along an axial direction; and a button linked at an intersected position of the electrode plates to horizontally move the electrode plates on the PCB for electrical transmission consideration, and essentially constantly engaging the spring for mechanical restoration consideration; wherein said button includes a wall portion surrounding the coil spring member so as to horizontally urge the coil spring inside to be compressed when the button is horizontally moved; wherein the button includes an operation portion exposed to an exterior for manual operation, and the operation portion is closer to the electrode plate than to the spring; wherein the printed circuit board defines a through hole below which the wall portion extends.
