The metal elastic piece 7 1 is provided with a plurality of fins 7 at a distance therebetween, and the fins 7 1 2 are respectively extended. The angled portion 7 is '3, the metal dome structure 7 is provided with an adhesive sheet 7 2 , and the adhesive sheet is 2 series; when the arrangement is attached to the metal elastic piece 7 1 , a circuit board 8 is disposed under the metal elastic piece 7 The circuit board 8 is provided with a plurality of positive connection bumps 8 1 and a negative connection bumps 8 2 at a distance from each other. The positive connection bumps 8 are connected to the corner portions 7 1 3 to fix the metal domes 7 1 on the circuit board 8 . The negative connection bumps 82 are corresponding to the inner faces of the protrusions of the metal domes. In addition, a button template 9 is disposed above the adhesive sheet. The button template 9 is provided with a button protrusion 9 i convex: 9 1 corresponds to the metal dome 7 , and the button template 9 is fixed on the pen board 8 The adhesive sheet 7 2 is fixed between the metal and the button bump 9 1. The button protrusion 9 is pressed down, and the metal elastic piece 7 is pressed down. The starting portion 7 1 1 ' makes the convex portion 7 1 1| The contact bump 8 2 contacts 'because the positive electrode of the circuit board 8 passes through the positive electrode connection 5 1313474, the bump 8 1 and the folded corner portion 7 1 qs and the negative electrode penetrates the gold i ' to make the positive electrode of the circuit board 8 Pressing and turning on. However, the above-mentioned conventional button metal stepping on the circuit board 8 needs to pass through the positive electrode structure 7, during the pressing process, 2, in order to make the metal bomb; t:; 81 and the negative connection bump 8 The number of workpieces is increased to: the nature is affected by the convex portion 71 "^2", the different piece 712 lacks the pressure of the bomb 1 and is not properly deformed, and the long-term use will cause damage, and its δ " The jig and the manual need to increase the cost of the adhesive sheet 72. On the metal shrapnel η, so that the inventor feels that the design of the captain can still be diligently studied and cooperated with the academic army. "Inch Gaibu, Shi, Yu Dong, proposed a reasonable design and effectively improved the above. SUMMARY OF THE INVENTION The main object of the present invention is to provide a metal dome switch connection: the metal piece is directly in contact with the circuit board, and does not need to be transparent: , the processing parts can be reduced, and the cost can be reduced; in addition, the effect can be saved, and the cost can be reduced and still adhered to the surface of the film. In order to achieve the above purpose, the present invention provides a metal 芸 switch. The metal dome switch is convexly arranged in the middle - according to the fortification area, the outer garden extends out of the body-formed connecting member, and the connecting member is fixed on the board to make the metal dome switch directly on the circuit board, The surface of the area is provided with a body-formed adhesive surface, so that the metal circle is closed to the pressing area, the connecting member and the adhesive surface-body forming structure 1313474 to enable further understanding of the hair ^ ^ ^ ^ ^ ^ ^ ^ ^ Please refer to the following about this issue. The details of the temple and the technical content, the drawings are only for reference and explanation, and the accompanying system. F used to limit the invention [embodiment] species eight: tea reading - map, third map and In the four figures, the present invention provides a pressing area U, the pressing is carried out, and the convex area 11 is 14; the metal piece is made of a metal sheet, and the pressing unit is a g shape, and the pressing area is丄After a connecting piece·| Pi, the left and right sides of the extension member 1 2, the money piece 丄2 includes - and the two telescopic portions 122 (such as elastic telescopic arms) *: 2 The lower part is folded in a direction: convex; the partial piece is translated into two sides by a metal piece, and the telescopic part 1 2 2-* is connected to the periphery of the pressing area 1 1 , and the other part (1) is the fixing part 121. A through hole i 2 3 is formed in the middle of the fixing portion am 2 1 , and the corresponding pressing portion i and the expansion and contraction region η and the expansion and contraction portion 122 are placed on the surface of the second and second cans 11 The bonding of the molding ^H according to the area 11, the connecting member 12 and the adhesive surface two: the dust-type, the far metal round cover switch 丄 is a one-piece formed workpiece. Version positioning: = anti-two There are four positioning bumps 2 on the periphery of the positive electrode, and the outer edge of the fixed portion 121_ is fixed; the block 21 is arranged in the middle to form a square-like shape. The four corners are placed against the positive pole of the positioning block 2 1313474, and then the positive electrode is fixed on the positive electrode. The metal dome is directly fixed to the electric 1 ' to align the fixing portion 1 2 1 with the electric solid. The crotch portion 1 2 1 is connected to the connecting plate 2 of the circuit board 2 through which the switch 1 passes. During the pressing process, the pressing area 1 is pressed down so that the pressing area 1 1 contacts the negative electrode of the circuit board 2, and the circuit board 2 is in contact with the pressing area 1 1 and the fixing portion 1 2 1 so that The positive and negative poles of the circuit board 2 are in a conducting state; in addition, the lower repeating region: the portion 122 is pressed by the pressing portion 11, and the appropriate shape is formed so that the connecting member 12 is not damaged. Because the 3 hp metal dome switch] is connected to the positive electrode connecting plate 2 similar to the conventional one, it is not necessary to connect the bump and the negative electrode to connect the bumps, which can reduce the fuel, 3, and 3. In order to reduce the cost, the pressing area 1 1 directly punches out the adhesive surface 丄 3 to make a similarly known adhesive sheet attached to the conventional golden fruit to eliminate the manufacture and adhesion of the adhesive sheet, thereby reducing the cost. In addition, the switch 1 is clamped to the pen board 2 by the connector i 2 having the function of elastic expansion and contraction, which can effectively prevent the occurrence of the split phenomenon. In addition, the positioning bump of the circuit board 2; "two: the metal dome switch 1 device is juiced on the circuit board 2, and the above is only the patent scope of the preferred invention of the present invention, so贝^ Μ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 3D is a perspective view of the metal dome switch of the present invention.
