目前市场上智能锁类型多样化，例如智能指纹锁、智能密码锁、智能感应刷卡锁等等，那该如何选择性能较好，使用寿命长的智能锁呢？其实，在智能锁中，微动开关可以说是占据重要地位的一个零部件。微动开关的好坏，直接决定了智能锁的使用体验是否符合消费者的需求。虽然是一个小小的部件，却起着不可替代的作用。

例如：欧姆龙微动开关，就具有锁舌的位置检测、反锁检测与防撬报警功能。

欧姆龙作为发展成为全球知名的自动化控制及电子设备制造厂商，其生产的欧姆龙智能锁用微动开关一直受到业内人士关注。

一、 可延长智能锁使用寿命

微动开关起着检测、反馈信息的作用，所以对智能锁中的微动开关寿命有一定要求，欧姆龙微动开关在测试过程中显示，其寿命高达100万次以上。不仅自身的寿命长，欧姆龙微动开关也得以延长了整台智能锁的使用寿命，足以满足智能锁70年的使用寿命。

二、 优选材质，不惧测试

在材质上，一些国产品牌使用的仅是普通合金铜，而欧姆龙微动开关的触点材料选用的是日本铍铜，导电性好，韧性高；并采用日本精密模具制造，整个微动开关具有防抖功能，避免了因抖动带来的误差。

在信赖性测试测到20W次的过程中，国产品牌弹片已经无法弹回，且触点处有氧化物产生。

三、 电阻小，选择多

智能锁往往是用干电池作为电源，所以要求电子元件的耗电量越小越好，欧姆龙智能锁用微动开关综合接触电阻仅为30毫欧，比一般的微动开关的接触电阻都小。与之相匹配的电线材料可以选用更细一些的电线，节省智能锁成本。

At present, there are various types of smart locks in the market, such as smart fingerprint lock, smart password lock, smart sensor swipe card lock, etc. How to choose smart locks with better performance and long service life? In fact, in the intelligent lock, the micro switch can be said to be an important part. The quality of the microswitch directly determines whether the use experience of the smart lock meets the needs of consumers. Although it is a small part, it plays an irreplaceable role.

For example, Omron microswitch has the functions of position detection of locking tongue, anti lock detection and anti pry alarm.

Omron as a well-known global manufacturer of automation control and electronic equipment, its production of OMRON smart lock microswitch has been concerned by the industry.

1、 Extend the service life of smart lock

Microswitch plays the role of detection and feedback information, so it has certain requirements for the life of microswitch in the intelligent lock. Omron microswitch shows that its life is more than 1 million times in the test process. Not only its own long life, Omron microswitch can also extend the service life of the whole intelligent lock, enough to meet the service life of the intelligent lock for 70 years.

2、 Optimized material, not afraid of testing

In terms of material, some domestic brands only use ordinary alloy copper, while the contact material of OMRON microswitch is Japanese beryllium copper, which has good conductivity and high toughness; and it is made of Japanese precision mold, the whole microswitch has the function of anti shake, avoiding the error brought by jitter.

In the process of 20W times of reliability test, the domestic brand shrapnel has been unable to bounce back, and oxide is generated at the contact.

3、 Small resistance, many choices

The smart lock usually uses dry battery as the power supply, so the smaller the power consumption of electronic components is, the better. The comprehensive contact resistance of micro switch for Omron smart lock is only 30 milliohm, which is smaller than the contact resistance of general micro switch. The matching wire material can choose finer wire to save the cost of intelligent lock.
