本發明之功效在於：透過拔除該等第一鍵腳或拔除該等第二鍵腳，獲得不同的按壓行程，節省替換該帽蓋的花費，更提升使用者的按壓手感。The function of the present invention is to obtain different pressing strokes by removing the first key pins or removing the second key pins, thereby saving the cost of replacing the cap and improving the user's pressing feel.

參閱圖2至圖4，本發明按鍵開關的一實施例，包含一載體1、一開關2、一薄膜面板3及一帽蓋4。Referring to Figures 2 to 4, an embodiment of the key switch of the present invention includes a carrier 1, a switch 2, a membrane panel 3 and a cap 4.

該載體1包括一基壁11，該基壁11具有一界定出一鍵孔112的錐面111。該錐面111為環狀且孔徑自開口朝外的一端朝開口朝內的另一端由大漸小。The carrier 1 includes a base wall 11 having a tapered surface 111 defining a keyhole 112 . The tapered surface 111 is annular, and the diameter of the hole gradually decreases from one end that opens outward toward the other end that opens inward.

該開關2用於輸出一電控訊號。該開關2設置於該載體1，並包括一本體21，及一沿一軸線方向X可移動地安裝在該本體21的按鍵22。該按鍵22可供觸壓，並具有一朝向該鍵孔112的抵靠面221。The switch 2 is used to output an electrical control signal. The switch 2 is provided on the carrier 1 and includes a body 21 and a button 22 movably mounted on the body 21 along an axis direction X. The key 22 can be pressed and has a resisting surface 221 facing the key hole 112 .

該薄膜面板3可供按壓且覆蓋在該載體1的該基壁11上，並包括一相對於該帽蓋4且可供按壓的凸面31。其中，該凸面31覆蓋該鍵孔112。The film panel 3 can be pressed and covers the base wall 11 of the carrier 1 , and includes a convex surface 31 relative to the cap 4 and can be pressed. The convex surface 31 covers the key hole 112 .

參閱圖3至圖5，該帽蓋4包括一適用於朝向該按鍵22且與該按鍵22相接觸的安裝面41、一相反於該安裝面41的觸控面42、二自該安裝面41朝該本體21方向延伸並平行間隔設置的第一鍵腳43，及二自該安裝面41朝該本體21方向延伸並與該等第一鍵腳43平行間隔設置的第二鍵腳44。Referring to FIGS. 3 to 5 , the cap 4 includes a mounting surface 41 adapted to face and contact the button 22 , a touch surface 42 opposite to the mounting surface 41 , and two mounting surfaces 41 . The first key pins 43 extend toward the main body 21 and are spaced parallel to each other, and the second key pins 44 extend from the mounting surface 41 toward the main body 21 and are spaced parallel to the first key pins 43 .

該觸控面42為弧口朝該按鍵22的曲面，且為一種拋光面。The touch surface 42 is a curved surface with an arc opening toward the button 22 and is a polished surface.

每一該第一鍵腳43可卸離地卡抵於該按鍵22，並包括一形成在一端且沿垂直該軸線方向X延伸的第一擋止部431，該第一擋止部431卡抵於該按鍵22反向於該觸控面42的該抵靠面221。每一該第一鍵腳43具有一沿該軸線方向X延伸的第一長度L1。Each first key foot 43 is detachably engaged with the button 22 and includes a first stopper 431 formed at one end and extending along the direction perpendicular to the axis X. The first stopper 431 engages with the key 22 . The button 22 is opposite to the abutment surface 221 of the touch surface 42 . Each first key pin 43 has a first length L1 extending along the axis direction X.

每一該第二鍵腳44可卸離地卡抵於該按鍵22，並包括一形成在一端且沿垂直該軸線方向X延伸的第二擋止部441，該第二擋止部441卡抵於該按鍵22反向於該觸控面42的該抵靠面221。每一該第二鍵腳44具有一沿該軸線方向X延伸的第二長度L2。其中，該第一長度L1大於該第二長度L2，且該第一長度L1與該第二長度L2的差值實質上為0.2公分。Each second key foot 44 is detachably engaged with the key 22 and includes a second stopper 441 formed at one end and extending along the direction perpendicular to the axis X. The second stopper 441 is engaged with the key 22 . The button 22 is opposite to the abutment surface 221 of the touch surface 42 . Each second key foot 44 has a second length L2 extending along the axis direction X. Wherein, the first length L1 is greater than the second length L2, and the difference between the first length L1 and the second length L2 is substantially 0.2 cm.

參閱圖3與圖5，值得一提的，該第一長度L1與該第二長度L2不相等，只要該等第一鍵腳43或該等第二鍵腳44能與該開關2的該按鍵22相配合而使該帽蓋4卡抵在該按鍵22即可。Referring to FIG. 3 and FIG. 5 , it is worth mentioning that the first length L1 and the second length L2 are not equal, as long as the first key pins 43 or the second key pins 44 can be connected with the button of the switch 2 22 cooperates with each other so that the cap 4 is stuck against the button 22 .

參閱圖6，本發明實施時，使用者可透過指腹觸壓該薄膜面板3的該凸面31，使該帽蓋4的該觸控面42與該凸面31相接觸，該安裝面41抵壓該按鍵22，就可以迫壓該按鍵22沿該軸線方向X移動，達到按壓該開關2的功能。Referring to Figure 6, when the present invention is implemented, the user can touch the convex surface 31 of the film panel 3 through the fingertips, so that the touch surface 42 of the cap 4 is in contact with the convex surface 31, and the mounting surface 41 presses The button 22 can be pressed to move along the axis direction X to achieve the function of pressing the switch 2 .

參閱圖3、圖5與圖6，在按壓的過程中，由於該等第一鍵腳43的該第一長度L1較長，與該開關2的該本體21間距較短，因此，按壓行程較短。若需求較長的按壓行程時，因該等第二鍵腳44的該第二長度L2較短，使用者可將該等第一鍵腳43折斷，使該等第一鍵腳43卸離，藉此，由於該等第二鍵腳44的該第二長度L2較短，與該開關2的該本體21間距較長，而能獲得較長的按壓行程。Referring to Figures 3, 5 and 6, during the pressing process, since the first length L1 of the first key pins 43 is longer and the distance from the body 21 of the switch 2 is short, the pressing stroke is longer. short. If a longer pressing stroke is required, since the second length L2 of the second key feet 44 is shorter, the user can break the first key feet 43 to detach the first key feet 43. Therefore, since the second length L2 of the second key legs 44 is shorter and the distance from the body 21 of the switch 2 is longer, a longer pressing stroke can be obtained.

應當注意的是，該等第一鍵腳43及該等第二鍵腳44的數量並不限於二，也可為三以上，只要該等第一鍵腳43與該等第二鍵腳44為等角設置，使用者拆除該等第一鍵腳43或該等第二鍵腳44時，該帽蓋4能達到平衡且卡抵在該開關2即可。It should be noted that the number of the first key pins 43 and the second key pins 44 is not limited to two, and can also be more than three, as long as the first key pins 43 and the second key pins 44 are They are arranged at equal angles. When the user removes the first key pins 43 or the second key pins 44 , the cap 4 can reach balance and be stuck against the switch 2 .

經由以上的說明，可將前述實施例的優點歸納如下：Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

1、該帽蓋4的該觸控面42為拋光面，可避免傷害該薄膜面板3。1. The touch surface 42 of the cap 4 is a polished surface to avoid damaging the film panel 3 .

2、該等第一鍵腳43與該等第二鍵腳44可卸離的結構，使該按鍵22因公差偏移而造成卡鍵時，透過卸除具有較長的該第一長度L1的該等第一鍵腳43，該等第二鍵腳44仍可與該按鍵22相互卡抵，使該按鍵22功能恢復正常，節省額外替換該帽蓋4的開銷。2. The detachable structure of the first key feet 43 and the second key feet 44 allows the key 22 to be jammed due to tolerance deviation by removing the longer first length L1. The first key pins 43 and the second key pins 44 can still engage with the button 22 , so that the function of the button 22 can be restored to normal, thereby saving the additional cost of replacing the cap 4 .

3、由於該第一長度L1和該第二長度L2不相等，因此，可以配合實務需求，選擇以該等第一鍵腳43或該等第二鍵腳44限制按壓行程，或適用更多種類的該按鍵22，只要該等第一擋止部431或該等第二擋止部441能卡抵在該按鍵22即可，不但能夠省去更換不同帽蓋的成本，且能夠增加該帽蓋4的實用性。3. Since the first length L1 and the second length L2 are not equal, according to practical needs, the first key feet 43 or the second key feet 44 can be selected to limit the pressing stroke, or more types can be applied. As long as the first stopper portions 431 or the second stopper portions 441 can snap against the button 22, it will not only save the cost of replacing different caps, but also increase the number of caps. 4. Practicality.

4、使用者按壓該開關2時，因該載體1的該錐面111的漸擴設計，可以容許指腹更深入該鍵孔112，不但能夠確實的按壓該按鍵22，且結構符合人體工學，而能有較佳的按壓手感。4. When the user presses the switch 2, due to the gradually expanding design of the tapered surface 111 of the carrier 1, the finger pulp can be allowed to penetrate deeper into the key hole 112. Not only can the key 22 be pressed reliably, but the structure is also ergonomic. , and can have a better pressing feel.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention.
