安装时，弹簧10装在推杆3上，再将推杆3装入螺纹套4的弧形导轨44中，第一卡板8和第二卡板9装入螺纹套4内的第一卡板槽43和第二卡板槽45中，密封圈7套在钮子心2的钮子心槽21，然后钮子套1套在钮子心2上，再将钮子心2装入螺纹套4中；将衬套6的卡扣61卡接在螺纹套4上的卡扣孔41上，螺帽5螺旋安装在螺纹套4的上端部同时压紧衬套6。当转动钮子时钮子的钮子心2上的钮子心凸轮24与推杆3的第一斜坡面33和第二斜坡面34配合打档复位，与推杆3的中心V形结构的锁定凹点32配合打档锁定，钮子心2上的第一钮子心23和第二钮子心22和第一卡板8、第二卡板9进行触碰的钮子的转动进行限位。
以下根据第一卡板8和第二卡板9在螺纹套4内的安装情况，说明本实施例的按钮开关操作机构提供的四种打档功能。
第一种：当不装第一卡板8和第二卡板9时，钮子的第一钮子心23和第二钮子心22左右打档行程都没有受阻，钮子心凸轮24在钮子心2向左或向右旋转时都能旋转到所述推杆3上的中心V形结构的锁定凹点32，起到锁定档位作用，即实现左右打档锁定。
第二种：当装上第一卡板8和第二卡板9时，钮子心2在左右旋转时，第一钮子心23和第二钮子心22左右行程都会受阻，钮子心凸轮24只能旋转到推杆3上的第一斜坡面33位置或第二斜坡面34位置，不能锁定，即实现左旋、右旋打档复位。
第三种：当不装第一卡板8，只装第二卡板9时，钮子心2左旋没有卡板限位，钮子心凸轮24能打到推杆3上的中心V形结构的锁定凹点32，起到锁定作用。钮子心2在右旋时由于有第二卡板9限位，钮子心凸轮24旋转到推杆3上的第二斜坡面34位置，不能起到锁定作用，即实现左旋打档锁定，右旋打档复位。
第四种：当不装第二卡板9，只装第一卡板8时，钮子心2右旋无卡板限位，钮子心凸轮24能打到推杆3上的中心V形结构的锁定凹点32，起到锁定作用， 钮子左旋时由于有第一卡板8限位，钮子心凸轮24只能旋转到推杆3上的第一斜坡面33位置，不能起到锁定作用，即实现左旋打档复位，右旋搭档锁定。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
