Simultaneously, An extension portion 530 bent upward and extending to the upper cover 2 is provided at the end of the conductive contact portion 53. When the key switch is in a natural state, the extension 530 is lifted up by the hook 211 of the upper cover 2 so that the conductive contact portion 53 is separated from the static contact piece 4, and the key switch is in an off state.

對於該第一扭簧5'的安裝，如第4、6圖所示，本實施例在所述基座1上分別形成有供該第一簧體51嵌入的一第一凹槽11、及供該導通接觸部53上下活動的一第一活動槽12，該連接端子52貫穿該第一凹槽11並電連接至PCB板。在該上蓋2上下移動的過程中，該導通接觸部53在該第一活動槽12內上下活動，從而實現與該靜觸片4接觸或分離，達到按鍵開關導通與斷開的目的。 For the installation of the first torsion spring 5', as shown in Figures 4 and 6, in this embodiment, a first groove 11 into which the first spring body 51 is inserted is formed on the base 1 and a first groove 11, and A first movable groove 12 for the conductive contact portion 53 to move up and down, the connecting terminal 52 penetrates the first groove 11 and is electrically connected to the PCB board. In the process of the upper cover 2 moving up and down, the conductive contact portion 53 moves up and down in the first movable groove 12 to achieve contact or separation with the static contact piece 4 to achieve the purpose of turning on and off the key switch.

本實施例將該第一扭簧5'的連接端子52與該靜觸片4直接焊接固定於PCB板10上，簡化了該基座1的結構，利於按鍵開關整體厚度更薄。 In this embodiment, the connecting terminal 52 of the first torsion spring 5'and the static contact piece 4 are directly welded and fixed on the PCB board 10, which simplifies the structure of the base 1 and facilitates the overall thickness of the key switch to be thinner.

實施例三：Embodiment three:

本實施例與實施例一或實施例二的主要區別在於，如第8、9圖所示，本實施例按鍵開關還包括一設置於該上蓋2與該基座1之間的平衡架3、及一發聲彈性件8，在所述平衡架3上設置有一按壓塊35，在所述基座1上設置有一導引斜面14，在自然狀態下，該發聲彈性件8的一端延伸至該按壓塊35下方，且位於該導引斜面14上方。 The main difference between this embodiment and Embodiment 1 or Embodiment 2 is that, as shown in Figs. 8 and 9, the key switch of this embodiment further includes a balance frame 3, which is arranged between the upper cover 2 and the base 1. And a sounding elastic member 8, a pressing block 35 is provided on the balance frame 3, and a guiding inclined surface 14 is provided on the base 1. In a natural state, one end of the sounding elastic member 8 extends to the pressing Below the block 35 and above the guiding inclined surface 14.

在本實施例中，具體的，如第9、10圖所示，所述發聲彈性件8為第二扭簧8'，具體的，第二扭簧8'由不銹鋼材質製成，即為不銹鋼扭簧，該第二扭簧8'主要由一第二簧體81、及一連接於該第二簧體81的彈動發聲部82組成，該彈動發聲部82延伸至該按壓塊35下方與該導引斜面14上方。當該平衡架3被按壓下移時，帶動該按壓塊35下移，該按壓塊35下壓該彈動發聲部82，下壓到一定位置時，該基座1上的導引斜面14導引該彈動發聲部82脫出該按壓塊35，該彈動發聲部82由於勢能釋放發生彈動而敲擊該基座1、或該基座1與該按壓塊35發出聲音，實現按壓發聲功能，聲音響，效果好。 In this embodiment, specifically, as shown in Figures 9 and 10, the sounding elastic member 8 is a second torsion spring 8'.

When the pressing block 35 is pressed down, the setting of the inclined surface 351 further guides the movement of the elastic sounding part 82 of the second torsion spring 8 ′ away from the pressing block 35.

對於該第二扭簧8'的安裝，如第6圖所示，本實施例在所述基座1上形成有供該第二簧體81嵌入的一第二凹槽15、及一供該彈動發聲部82上下彈動的第二活動槽16。在該平衡架3上的按壓塊35受壓下移的過程中，該彈動發聲部82受壓在該第二活動槽16內活動，脫出該按壓塊35後，在該第二活動槽16內彈動實現發聲效果。 For the installation of the second torsion spring 8', as shown in Figure 6, in this embodiment, a second groove 15 for the second spring body 81 to be inserted is formed on the base 1, and A second movable groove 16 for the elastic sound generating part 82 to move up and down. When the pressing block 35 on the gimbal 3 is pressed down and moved, the elastic sound generating part 82 is pressed to move in the second movable groove 16, and after the pressing block 35 is pulled out, it moves in the second movable groove 16 inner bounce to achieve sound effect.
