Technical Problem
[0003]按钮式点火开关已经替代传统钥匙式点火开关成为主流方案，按钮式点火开关长期使用后，点火开关缝隙处在按压过程中会进入灰尘，并会随着下次按动被带入点火开关内部，这可能会使灰尘附着在开关的触点或导电部件上，可能会引发接触不良，影响电流传递，导致影响点火开关正常使用的问题出现
Benefits of technology
[0012]本实用新型的有益效果在于：本实用新型使用时，驾驶员按下开关按键使其向下移动，带动触点A和凸环向下移动，触点A会与触点B接触，使电路接通，凸环会挤压弹簧，使其在环槽内压缩并储存弹性势能，在此过程中，空腔A内空气受压进入通气槽，再从通气槽进入气囊内部，气囊充气后填满空腔B；点火完成后，驾驶员松开开关按键，弹簧会回弹释放弹性势能，推动凸环和开关按键复位，使触点A与触点B分离，起到了自动复位的作用，此时气囊内部空气会重新进入空腔A，形成类似活塞的运动过程，在此过程中，空腔A内部始终保持密闭，起到了避免灰尘与水汽进入的作用，从而避免触点接触不良的情况出现；综上所述，本实用新型拥有良好的密闭性，可以有效阻隔灰尘与水汽，具备了避免触点接触不良的有益效果，解决了点火开关缝隙处在按压过程中会进入灰尘，并会随着下次按动被带入点火开关内部，这可能会使灰尘附着在开关的触点或导电部件上，可能会引发接触不良，影响电流传递，导致影响点火开关正常使用的问题。
