The circuit board 2GG is provided with four contacts 202 and a plurality of mounting holes 204 corresponding to the four contact columns (10). One side of the keycap 104 is a pressing surface 142 for accepting a pressing operation by a user. The four contact columns 1〇8 are protrusions having a cross-shaped cross section, and a uniform 77 is disposed on the other surface of the keycap 1Q4 for contacting the contacts 2〇2 on the circuit board 200. The edge of the keycap 1 () 4 extends vertically to form a cap / σ 144. The four guard posts 11 are cylindrical protrusions respectively located on the bristle 144 of the radius of the four contact columns 108 in the key. In the present embodiment, the guard column 11G is opposite to the pressing surface 142. The height is greater than the height of the touch column 108 relative to the pressing surface M2. The four elastic arms 1〇6 have a strip-shaped rib shape, and one end of the elastic arm 1〇6 is formed by the brim 144 extending outward in the radial direction of the key cap 1G4, and the four elastic I·I I 106 are evenly distributed. The key caps 1〇4 are staggered with the four contact columns, that is, the radius of each of the contact columns (10) is the same as the radius of the adjacent two elastic arms 106. The other ends of the four elastic arms 1〇6 are respectively connected to the inner wall 122 of the rectangular hollow frame 102. 8 200921463 In the present embodiment, the end of the four elastic arms 1〇6 connected to the frame 1〇2 is folded and folded, so that the elastic arms 1〇6 are perpendicularly connected to the inner wall 122 of the frame 1〇2, and four The elastic arms 1〇6 are connected to the opposite two 122s of the frame 1〇2. The frame body 102 is provided with a plurality of mounting portions 124 corresponding to the plurality of mounting holes 2〇4 of the circuit board 200. The mounting holes 204 and the mounting portion 124 can be filled by screws, rivets, buckles or other fixing means. The fixing to the circuit board 200 is fixed. 〇〇 Please refer to FIG. 3 and FIG. 4 , which are cross-sectional views of the assembled button device 1 , wherein FIG. 3 is a schematic view of the structure of the button in an unpressed state, and FIG. 4 is a schematic structural view in a pressed state. As can be seen from Fig. 3, the contact column 1〇8 does not touch the contact 2〇2 on the circuit board 2〇〇, and the guard column is separated from the circuit board 200, and the elastic arm is employed in a non-deformed state. Referring to FIG. 4, after the multi-directional button 100 is pressed, the elastic arm 1〇6 is elastically deformed, the key cap 104 is tilted, and the contact column corresponding to the force point (10) C V. The moving sub-contact circuit board 2〇 The corresponding contact on the 逝 is gone. At the same time, the guard column corresponding to the contact post 108 is placed against the top, so that the touch pressure; ^ irrigation cannot continue to move downward, that is, no greater pressing force is applied to the contact 202 to avoid Contact 202 is damaged by excessive weight pressing. Baoqi: Position 'such as the touch column 1〇8 or near the key 202 日士抿顶 ^ 'Total' as long as it can be used to touch the waste contact 202 to the top of the circuit board 2 . - The above-mentioned ^-type button is fixed by the frame and the circuit board is fixed, and the key cap 1〇4 is positioned in the frame by the number of elastic arms 1〇6, and the rotation or offset occurs when used in 200921463 The situation: ^ control, extending the life of the button. And the private body 102 is only used as a multi-directional button (10) road plate 200 or other shells in the shape of the road, as long as it can dream of solidification outside its wenwan b magical hunting by the solid elastic arm 1〇6 That is, the component can be a screw hole connected to the elastic arm 106, such as two solids: When the component is a screw hole, the screw can be screwed or the second solid is fixed: the button 100 is fixed to the Thunder and the ten-sweet from the ±, The yoke card illusion r plate or other housing; when the fixing component is a card spoon, the card can be hunted by the card: the multi-directional (four) 1GG is fixed. The deformation of the four (four) sexual arms 106 of the elastic arms (10) is caused by the movement of the rest 108, and the deformation of the four elastic arms (10). ~U is also advantageous for the operation of the button. The person skilled in the art is only used to explain the present invention, and the implementation of the ^ is used as the limit of the present invention. Within the scope of the spirit of Benjamin, the appropriate changes and changes in each of the works are all within the scope of the month.
