Connected, the other ends of the two terminals 53 are connected to the PCB board 6.
具體的，電阻應變片52就是一個電阻，在靜態條件下，電阻應變片52的電阻很大，故兩根引線54內的電流很小，該狀態下鍵盤開關無法導通，當在彈性敏感元件51的有效面積上施加壓力後，電阻應變片52的電阻會隨著壓力的增大相應的減小，當減小到一定程度時，鍵盤開關就會導通，而且隨著電阻應變片52的阻值的減小，鍵盤開關的電流也會隨之相應的增大，從而使得遊戲者可通過適當的按壓於鍵盤開關來調節電腦遊戲中人或物的移動速度，本新型一方面避免了鍵盤開關因觸點變形、氧化造成接觸不良，提高了鍵盤開關的使用壽命；另一方面可實現鍵盤開關電流線性的輸入輸出，只需使用很小的力，便能導通按鍵開關，提高了按鍵開關的靈敏度和通用性。 Specifically, the resistance strain gauge 52 is a resistor. Under static conditions, the resistance of the strain gauge 52 is large, so the current in the two leads 54 is small, and the keyboard switch cannot be turned on in this state, when the elastic sensitive component 51 is present. After the pressure is applied to the effective area, the resistance of the strain gauge 52 decreases correspondingly with the increase of the pressure. When the pressure is reduced to a certain extent, the keyboard switch is turned on, and the resistance of the strain gauge 52 is increased. The reduction of the keyboard switch current will also increase correspondingly, so that the player can adjust the moving speed of the person or object in the computer game by appropriately pressing the keyboard switch, and the novel avoids the keyboard switch The contact deformation and oxidation cause poor contact, which improves the service life of the keyboard switch.

Being crushed increases the service life of the elastic sensitive member 51.
