本实施例充分利用驱动件 2与钢针之间摩擦系数小， 驱动件 2与钢针间 难以进灰尘， 即便是有灰尘颗粒进入， 在一硬（钢针）和一软（驱动件） 的 加持下灰尘也不会卡死驱动件 2。 本实施例充分利用了钢与塑胶间摩擦小， 对 灰尘有包含性， 从而提高了开关的抗灰尘性能。
为了更好的使得按钮 1 复位， 本实施例中的复位弹簧可以包括： 水平复 位弹簧 6和垂直复位弹簧 7。
优选的， 请参阅图 1， 图 2或图 3， 水平复位弹簧 6可以安装在按钮 1的 槽内， 垂直复位弹簧 7可以安装在上盖 5与按钮 1之间。 在撤消按钮 1的外 力后， 水平复位弹簧 6可以促使驱动件 2恢复到中间位置， 垂直复位弹簧 7 可以促使按钮 1 复位， 使得本实施例中的按钮可以回复到原始位置， 保持开 关表面纯平， 提升了开关的美观性。 并且， 在撤销按钮 1 的外力后， 水平复 位弹簧 6可以促使驱动件 2回复到按钮 1的中间位置， 当再次按下按钮 1时， 驱动件 2上的另一个驱动牛角 22会碰撞摆杆 4上的另一个碰撞块 41，促使摆 杆 4再次偏转以改变开关的状态， 可以提供可靠有效的保证。
可选的， 为了更好的实现摆杆 4的功能， 本实施例中的摆杆 4与上盖 5 釆用轴孔配合连接。 其中， 摆杆 4的偏转可以改变开关的通断状态。
下面对本实施例中按钮开关的具体运动过程进行详细说明：
当按下按钮 1时， 按钮 1会绕着上盖 5上的第一孔 51旋转， 并带动装在 按钮 1上的驱动件 2—起往下， 同时压缩垂直复位弹簧 7。
请参阅图 3和图 6，图 6是本实施例中按钮式复位开关的第一状态示意图。 当驱动件 2下到一定的位置时， 驱动件 2上的驱动牛角 22会接触到摆杆 4上 的碰撞块 41。 详细可参见图 7， 图 7是图 6中 D1的局部放大图。
这时如果驱动件 2随着按钮 1继续往下， 驱动件 2受碰撞块 41反作用于 驱动牛角 22的反作用力， 将在驱动牛角 22和碰撞块 41的作用下沿着连接件 3向左平行移动，从而确保驱动件能始终可靠有效的驱动摆杆， 并压缩水平复 位弹簧 6。 具体可参阅图 8和图 9， 图 8是本实施例中按钮式复位开关的第二 状态示意图， 图 9是图 8中 D2的局部放大图。
请参阅图 10， 图 10是本实施例中按钮式复位开关的第三状态示意图。 继 续按动按钮 1， 驱动件 2会随着按钮 1继续往下运动， 直到驱动摆杆 4偏转， 使得摆杆 4驱动银桥旋转， 并且摆杆 4上的碰撞块 41通过驱动件 2上的驱动 牛角 22继续驱动该驱动件 2沿连接件 3向左平行移动， 并随按钮 1带着驱动 件 2往下一直持续到摆杆 4旋转到另一个稳定状态。 详细可参见图 11， 图 11 是图 10中 D3的局部放大图。
若此时撤去按钮 1上的压力， 按钮 1在已被压缩的垂直复位弹簧 7的作 用下会绕第一孔 51旋转向上运动， 并带着驱动件 2—起往上运动， 同时驱动 件 2在被压缩的水平复位弹簧 6的作用下沿连接件 3向右移动， 直到中间起 始位置。 按钮 1在垂直复位弹簧 6作用下向上旋转运动， 直到按钮 1停止运 动。 其中， 可以在按钮 1上设有卡勾， 在上盖 5上设有限位扣， 该卡勾可以 与该限位扣钩住， 使得按钮 1停止运动。
以上过程即完成本实施例中的开关从一个稳定状态到另一稳定状态的过 程， 反之亦然。
其中， 本实施例中每一次按压按钮 1都能可靠的使得驱动件 2上的驱动 牛角 22碰撞摆杆 4上的一个碰撞块 41， 并避开另一个碰撞块 41， 可以保证 驱动件 2能够可靠地传递驱动力， 并且对各零部件的制造精度要求低。 此外， 本实施例中的驱动件 2只有两个工作位置， 可以简化开关的运动过程， 使得 开关的运动更顺畅， 性能更稳定。
本实施例中， 通过按下按钮 1可以切换驱动件 2和摆杆 4的工作状态， 与此同时， 在每一个工作位置上， 连接件 3可以保证按钮 1为驱动件 2提供 稳定的驱动力， 可以保证驱动件 1 停留在正确的位置上， 使得开关的性能更 加稳定可靠， 还可以降低组成按钮开关的各部件的制造精度要求， 抗灰尘能 力更强， 并且可以减少零件数量以降低生产成本。
本实施例中按钮式复位开关中的驱动件 2 的左右运动至始至终是沿着连 接件 3进行的， 其与按钮 1无任何接触， 且有关面线均有较大的间隙， 同时 驱动件 2釆用带有自润滑的塑胶材料， 极大的降低了驱动件 2与连接件 3间 的摩擦阻力， 这就保证了驱动件 2的左右运动十分顺畅。 此外， 连接件 3表 面光滑且表面积小， 大颗粒的灰尘无法附着， 提高了系统抗灰尘能力， 同时 连接件 3与驱动件 2—硬一软的配合有着较好的抗灰尘能力， 并且连接件 3 与驱动件 2釆用两端短插入配合， 这种配合不仅精度高， 并且不易被卡死。
此外， 本实施例中的按钮式复位开关还可以设置开关状态指示的辅助功 能。
可选的， 可以在上盖 5上安装指示器 8， 用于指示开关状态， 具体可参阅 图 3。 指示器 8的一端是个拨球， 另一端是指示面板， 指示面板表面由两种不 同颜色分割， 不同颜色表示开关的不同状态。
其中， 指示器 8的拨球被卡入摆杆 4的拨叉中， 当摆杆 4从一个稳定状 态变化到另一个稳定状态时，摆杆 4的拨叉通过指示器 8的拨球拨动指示器 8 从一边摆向另一边， 反之亦然。 本实施例中通过按钮 1 上的观察孔能轻易的 看到指示器 8的变化， 从而得知开关当前状态。
由上可知， 本公开包括按钮 1、 驱动件 2、 连接件 3、 摆杆 4、 上盖 5和 用于促使按钮 1复位的复位弹簧； 按钮 1与上盖 5连接， 驱动件 2通过连接 件 3与按钮 1连接， 按钮 1在被按下时通过连接件 3带动驱动件 1偏转， 驱 动件 1在偏转过程中驱动摆杆 4偏转以控制开关的通断。 本实施例中的按钮 式复位开关具有简单的结构， 驱动性能稳定， 并且对各组成部件的制造精度 要求低。 以上对本公开所提供的一种按钮式复位开关进行了详细介绍， 对于本领 域的一般技术人员， 依据本公开实施例的思想， 在具体实施方式及应用范围 上均会有改变之处， 综上所述， 本说明书内容不应理解为对本公开的限制。
