  在这个电器化的时代，各种各样的电器产品让我们的生活更加便利，也提高了我们的生活品质，但我们常常也会听到抱怨声某某电器的开关又坏了电器没法工作了，确实也令人抓急，可见开关作用之大，各类电器想正常工作还真得通过开关控制，小小的开关每次使用都是一次轻微磨损，记录着电器的使用次数，也决定着电器的使用寿命。
  今天来说说在我们日常生活中常见的轻触开关，它小巧轻便，外观美观使用寿命又长，因而在我们生活中应用很广泛，比如遥控器、电视机、微波炉、电饭煲、数码相机、MP3、MP4、音响等等产品，轻触开关是由嵌件、基座、弹片、按钮、盖板组成，防水轻触开关会在里面加上一层聚酰亚胺薄膜，其中弹片可以说是轻触开关的心脏部件，我们常常会谈开关手感如何，就是由弹片来控制的，它的质量好坏对轻触开关的使用次数有影响，也间接影响了电器产品的使用寿命。
  轻触开关的弹片有圆形、方形、三角形、椭圆形等，不同形状的弹片行程不同，用在轻触开关内部三角形和椭圆形很少有见，一般为方形弹片和圆形弹片，方形和圆形在形状、操作手感和行程上都很有优势，其中圆形用的最多，它是各弹片形状中行距最短的一种。弹片的材质有磷铜和不锈钢两种，国内很多厂家会选择磷铜弹片，因为磷铜弹片性价比高可以节约成本，缺点是弹片耐温不如不锈钢，经过炉温后会产生改换，很容易缩水使得手感变得不好，而不锈钢弹片本钱就比较高，却不易变形，精密度高，手感不错，按键舒适，使得轻触开关使用寿命更长久。

  给大家推荐几个手感不错的国内轻触开关品牌供参考，正泰、德力西、alps.星坤XKB，其中alps品牌轻触开关耐高温，使用寿命长，具有防水性，星坤XKB品牌开关采用的是台湾及日本进口原材料不锈钢弹片，可以保证每个开关不低于十万次以下的寿命，总之轻触开关弹片至关重要，在购买时一定记得了解清楚，问清弹片材质，选择合适的轻触开关，才能保证我们的电器产品用起来得心顺手。现在国内的成熟越来越多客户将进口alps的轻触开关替换成星坤xkb品牌.在性价和交期上更符合国内需求，毕竟xkb品牌完全能满足小型轻触开关带点容易偏移的市场需求.

What shrapnel is used for the tact switch

In this age of electronics, a variety of electrical products make our life more convenient and improve our quality of life,but we often hear someone complaints that the appliance is broken again even stop working,that's terrible and none of us want to meet this situation,it can be seen that the function of the switch is so great that all kinds of electrical appliances can really be controlled by the switch if they want to work normally.The small switches record the number of times an appliance is used and determine its life.

Here we're going to talk about the tact switch that we see in everyday life,they are compact and light, beautiful in appearance and long in service life, so they are widely used in our life,such as remote control, TV, microwave, rice cooker, digital camera, MP3, MP4, audio and other products.The tact switch is composed of insert, base, shrapnel, button and cover plate. The waterproof tact switch will add a layer of polyimide film inside,among these And the shrapnel is the heart part of a tact switch,we often talk about how the switch feels, which is controlled by the shrapnel,its quality affects the use times of the tact switch and indirectly affects the service life of electrical products.

The shrapnel of tact switch has circle, square, triangle, ellipse, etc., and different shapes with different travel.The inner triangles and ellipses are rarely seen in the tact switch, generally we can see square shrapnel and round shrapnel.Squares and circles have advantages in shape, handling and stroke.Round shrapnel is used most,it is one of the shortest line distances of each shrapnel shape.The material of the shrapnel is phosphorous copper and stainless steel,many domestic manufacturers will choose phosphocopper shrapnel, because it is cost-effective to reduce costs,the drawback is that the shrapnel is not as resistant to temperature as stainless steel,after the furnace temperature will produce a change, easy to shrink so that the handle becomes bad,while stainless steel shrapnel cost is higher, but not easy deformation,the stainless steel shrapnel has high precision, good feel and comfortable key, which makes the tact switch have a longer service life.

Here I recommend some domestic tact switch brands that feel good to everybody for reference,CHINT,DELIXI,ALPS,XKB.ALPS brand tact switches have the advantages of high temperature resistance, long service life, and waterproof,XKB switches use stainless steel shrapnel imported from Taiwan and Japan,each switch can be guaranteed to have a life of no less than 100,000 times.Now more and more domestic customers have replaced the tact switch of imported ALPS with XKB brand,in terms of sexual price and delivery date, it is more in line with domestic demand,after all, the XKB brand is perfectly capable of meeting the market demand for small tact switches with easy deflection.


In short the tact switch shrapnel is very important,be sure to know the material of the shapnel when buying,choosing the right light touch switch to make sure our electrical products work well.
