为了便于本领域技术人员理解，下面将结合附图以及具体实施例对本实用新型构思进行进一步详细描述。The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
如附图1、2所示，本实施例揭示的高可靠性微动开关整体外形与现有微动开关一致或相近，同样包括底座1、安装于底座1上的上盖2，在底座1中穿插固定有公共端子31、常开端子32以及常闭端子33三个金属端子3，金属端子3下端延伸出底座1外，用于穿插在外部线路板上实现电导通。金属端子3上端延伸出底座1上方，在金属端子3上端安装有弹性导电片4，弹性导电片4一端卡于公共端子31上端，另一端通过自身弹性形变与常闭端子接触。在上盖2上设置有一按钮5，按钮5下压推动弹性导电片与常闭端子33之间分离，使弹性导电片4与常开端子32接触实现电路切换。当释放按钮5后，弹性导电片4在自身弹力的作用下恢复至与常闭端子33接触。本实施例中，公共端子31、常开端子32以及常闭端子33的上端厚度均大于自身下端厚度，详细如附图3所示。当然，也可以只设计为仅公共端子31上端厚度均大于自身下端厚度。弹性导电片4与公共端子31卡接部位接触长度大于金属端子3下端厚度，同时弹性导电片4与常开端子、常闭端子之间实现面接触。As shown in FIGS. 1 and 2, the overall shape of the high-reliability micro switch disclosed in this embodiment is identical or similar to that of the existing micro switch, and also includes a base 1, an upper cover 2 mounted on the base 1, and the base 1 The three metal terminals 3 of the common terminal 31, the normally open terminal 32 and the normally closed terminal 33 are interspersed, and the lower end of the metal terminal 3 extends out of the base 1 for insertion into an external circuit board for electrical conduction. The upper end of the metal terminal 3 extends above the base 1. At the upper end of the metal terminal 3, an elastic conductive sheet 4 is mounted. One end of the elastic conductive sheet 4 is clamped to the upper end of the common terminal 31, and the other end is in contact with the normally closed terminal by elastic deformation. A button 5 is disposed on the upper cover 2, and the button 5 pushes down to separate the elastic conductive piece from the normally closed terminal 33, so that the elastic conductive piece 4 is in contact with the normally open terminal 32 to realize circuit switching. When the button 5 is released, the elastic conductive sheet 4 returns to contact with the normally closed terminal 33 by its own elastic force. In this embodiment, the thicknesses of the upper ends of the common terminal 31, the normally open terminal 32, and the normally closed terminal 33 are both greater than the thickness of the lower end thereof, as shown in detail in FIG. Of course, it is also possible to design only that the thickness of the upper end of the common terminal 31 is greater than the thickness of the lower end of the self. The contact length of the elastic conductive sheet 4 with the common terminal 31 is greater than the thickness of the lower end of the metal terminal 3, and the elastic conductive sheet 4 is in surface contact with the normally open terminal and the normally closed terminal.

After testing, the structure of the micro switch has a service life of more than 20 million times. And the structure retains the size specification of the lower end of the metal terminal, which improves the compatibility of the micro switch with the existing line installation.

This structure also increases the positional stability of the elastic conductive sheet 4 on the common terminal 31.
为了便于各金属端子顺利插入底座1中，并且保证各金属端子插入位置的准确、一致，在金属端子上端和下端之间具有一卡台312。
In order to facilitate the smooth insertion of the metal terminals into the base 1, and to ensure the accuracy and consistency of the insertion positions of the metal terminals, a card table 312 is provided between the upper end and the lower end of the metal terminal.
至于如何使金属端子上端厚度大于下端厚度，可采用厚度较厚的五金坯料冲压，冲压时使金属端子上端保留较厚的厚度，下端则成型为较薄的厚度。As for how to make the thickness of the upper end of the metal terminal larger than the thickness of the lower end, a thicker metal blank can be used for stamping, and the upper end of the metal terminal is kept thicker when punching, and the lower end is formed into a thinner thickness.
另外，再如附图4所示为金属端子另一结构示意图。为了使金属端子上端厚度大于下端厚度，也可通过弯折重叠金属端子上端实现，具有相同的技术效果。In addition, as shown in FIG. 4, another structural diagram of the metal terminal is shown. In order to make the thickness of the upper end of the metal terminal larger than the thickness of the lower end, it can also be realized by bending the upper end of the overlapping metal terminal, and has the same technical effect.
以上所述实施例仅表达了本实用新型的实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。

It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
