在一实施例中，请一并参考图5及图6所示，分别为本实用新型中消音体采用上弹性片以及下弹性片的剖视图以及消音体采用弹性套的剖视图，消音体9包括上弹性片901以及下弹性片902，上弹性片901以及下弹性片902相对设置于活动腔8的腔壁，例如，上弹性片901和下弹性片902采用粘接或者嵌入安装的方式分别固定于上盖1内壁以及底座2顶部，簧片5的活动端502位于上弹性片901以及下弹性片902之间，如此一来，通过上弹性片901以及下弹性片902覆盖簧片5的活动端502与活动腔8之间的接触面。在一实施例中，消音体9包括弹性粒903，具体的簧片5的活动端502开设有一卡设槽503，弹性粒903通过卡设槽503实现嵌设于簧片5的活动端502，其中弹性粒903位于活动端502与活动腔8的接触点的位置，如此一来，可节约生产材料，降低生产难度以及生产成本。在又一实施例中，消音体9包括弹性套904，其中弹性套904与簧片5的活动端502形状匹配，具体的弹性套904套于簧片5的活动端502，实现对活动端502的全包围，进而实现簧片5工作时的静音效果，降低生产难度，有效提高生产效率。
在一实施例中，请继续参考图1、图3及图4所示，本实用新型的静音微动光学开关还包括第二支架4，第二支架4固定于底座2远离第一支架3的一端，第二支架4的顶端位于安装腔内并设置有限位板401，具体的，限位板401采用倒L型设计，其中簧片5的活动端502位于限位板401与底座2之间，此时活动腔8由限位板401与底座2之间的活动区域构成，通过调节限位板401的厚度可实现对活动腔8空间大小的调节，从而实现对簧片5的活动端502的移动范围进行调节，进而对簧片5的形变范围进行调节，同时可防止簧片5变形过度造成损坏。
在本申请中，请一并参考图7所示，其为本实用新型中第一支架和第二支架为一体成型的结构示意图第一支架3和第二支架4与底座1可采用一体成型结构，具体的，第一支架3和第二支架4与底座1采用注塑成型的方式实现一体成型，如此一来，有效提高第一支架3和第二支架4与底座1之间的连接的稳固性。当然的，第一支架3和第二支架4与底座1可采用分体式结构设计，例如，第一支架3和第二支架4采用金属端子结构，第一支架3和第二支架4采用卡接或抵接的方式固定于底座1的两端。
在一实施例中，请参考图7所示，本实用新型的静音微动光学开关还包括第二支架4，其中第一支架3以及第二支架4的底端向下延伸并形成用于插接于线路板的插接部结构，利用第一支架3以及第二支架4的插接部实现本实用新型的静音光学微动开关安装于线路板上，并且通过插接部实现焊接固定。
在一实施例中，请继续参考图1、图3及图4所示，控制按钮6上绕设有防尘兜601，防尘兜601上开设有防尘槽6011防尘兜601防尘兜601防尘兜601防尘槽6011，当本实用新型的静音光学微动开关处于自然状态下，控制按钮6穿设上盖1，其中防尘兜601抵接与上盖1低壁，进而通过防尘槽6011对控制按钮6于上盖1之间的间隙进行密封，使得灰尘从间隙进入开关内时落入防尘槽6011内，避免灰尘对开关内部的其他部件造成影响，有效提高本实用新型的静音光学微动开关的可靠性。
在本申请中，请一并参考图8所示，其为本实用新型中控制按钮与导通杆为分体式结构的结构示意图，控制按钮6与导通杆7之间可采用一体成型结构，例如，导通杆7的顶端固定控制按钮6的底部，如此一来，有效提高控制按钮6与导通杆7之间的力传导响应速率。当然的，控制按钮6与导通杆7之间亦可采用分体式设计，例如，导通杆7固定于簧片5的活动端502，控制按钮6抵接簧片5的固定端501的表面，当按压控制按钮6时，簧片5整体下压并朝向活动端502发生形变，带动导通杆7向下移动，当撤控制按钮6的压力时，簧片5恢复从而带动导通杆7向上移动，从而实现控制按钮6与导通杆7之间的联动。
本实用新型还提供一种开关模组，请参考图4及9所示，其中图9为本实用新型中开关模组的爆炸示意图，开关模组包括线路板10以及设置于线路板10上的对射管11，还包括：本实用新型实施例1所述的静音光学微动开关，静音光学微动开关设置于线路板10上，对射管11设置于对射通道201的两侧，具体的，对射管11具有发射管以及接收管，发射管以及接收管分别设置于对射通道201的两侧，并且发射管以及接收管之间的光学回路位于对射通道201内，本实用新型的开关模组通过导通杆7对位于对射通道201内的光学回路进行干涉阻断，从而时间开关的通断。其中底座2的底部还设置与对射管11匹配的安装槽203，对射管11安装于安装槽203内，实现将对射管11隐藏于底座2内，有效提高对射管11的工作稳定性，并且可减少线路板10的尺寸设计。
综上所述，本实用新型的静音光学微动开关及开关模组，其簧片设置有固定端以及活动端，其中簧片的活动端设置于消音体之间，或者消音体设置于簧片的活动端上，当开关工作时，其中簧片的活动端通过消音体与开关内部表面抵接，利用消音体降低或消除簧片与开关内部碰撞产生的声响，使得本实用新型的光学微动开关达到静音效果，适用安静环境中。
