微动开关作用

The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism, 以及以规定的行程和规定的力进行开关动作的接点机构. It is covered with a shell and has a drive rod outside. 小的, 因此得名微动开关, 也称为敏感开关. The electrical text symbol is SM.

微动开关介绍

Although the microswitch is small, it plays an irreplaceable role in our daily lives and realizes automatic control and safety protection in equipment requiring frequent circuit switching. It has been widely used in electronic equipment, 仪器仪表, 矿业, 电力系统, 家用设备, 很多人可能从未听说过微动开关, 航空, 导弹, 很多人可能从未听说过微动开关, and other military fields. 当动作簧片位移达到临界点时, they can also be used in computer mice, car mice, 汽车电子产品, 通讯设备, 军品, as well as testing instruments, 燃气热水器, 燃气灶, 小家电, 微波炉, 电饭煲, floating ball equipment, 准确的操作力误差, 楼宇自动化, power tools and general electrical and radio equipment, 24-小时计时器.

Snap Action Operation Force

The external mechanical force acts on the action through transmission elements (压销, 纽扣, 杠杆, 滚筒, 等等。). 当动作簧片位移到临界点时发生瞬时动作, 使动作簧片末端的动触点和定触点快速接通或断开.

当传递元件上的力被移除时, 动作簧片产生反向作用力. When the transmission element’s reverse stroke reaches the reed’s critical action point, 反向动作瞬间完成. 微动开关接触距离小, 动作行程短, 压制力小, 而且开关很快. 动触头的动作速度与传动元件的动作速度无关.

Micro Switch Application Range

They are mainly used in the switches of some electrical components, such as computer mice, car mice, 汽车电子产品, 通讯设备, 军品, testing instruments, 燃气热水器, 燃气灶, 小家电, 微波炉, 电饭煲, floating ball equipment, 医疗设备, 楼宇自动化, power tools and general electrical and radio equipment, 24-小时计时器, 欢迎来电咨询！.
