按钮开关作为电气领域一种基础而关键的元件，扮演着举足轻重的角色。它们不仅控制着电路的通断，还直接影响着设备的运行状态和安全性。 按钮开关其基本功能包括：

　　As a fundamental and critical component in the electrical field, button switches play a pivotal role. They not only control the on/off of the circuit, but also directly affect the operating status and safety of the equipment. The basic functions of a button switch include:

　　1.通断控制：按钮开关最直接的作用就是控制电路的通断，使电气设备能够按照预定的程序启动或停止。

　　On/off control: The most direct function of a button switch is to control the on/off of the circuit, enabling electrical equipment to start or stop according to a predetermined program.

　　2.信号传递：在某些复杂系统中，按钮开关还承担着信号传递的任务，通过不同的按压方式（如长按、短按、双击等）向系统发送不同的指令。

　　Signal transmission: In some complex systems, button switches also undertake the task of signal transmission, sending different instructions to the system through different pressing methods (such as long press, short press, double-click, etc.).

　　3.安全保护：部分按钮开关设计有自锁或互锁功能，以防止误操作导致的设备损坏或人员伤害。

　　Safety protection: Some button switches are designed with self-locking or interlocking functions to prevent equipment damage or personnel injury caused by misoperation.

　　按钮开关种类繁多，按照不同的分类标准可以分为以下几类：

　　There are various types of button switches, which can be classified into the following categories according to different classification standards:

　　1.按动作方式分类：可分为常开型（NO，Normal Open）、常闭型（NC，Normal Close）和转换型（Changeover）开关。常开型开关在未按下时断开电路，按下时接通；常闭型则相反；转换型开关则能在两种状态间切换。

　　Classified by action mode: It can be divided into normally open (NO), normally closed (NC), and changeover switches. A normally open switch disconnects the circuit when not pressed and connects when pressed; The normally closed type is the opposite; The conversion switch can switch between two states.

　　2.按防护等级分类：根据IP等级（Ingress Protection Rating），按钮开关可分为防水、防尘等不同级别的产品，以适应不同的使用环境。

　　Classified by protection level: According to the Ingress Protection Rating, button switches can be classified into different levels of products such as waterproof and dustproof to adapt to different usage environments.

　　3.按安装方式分类：有面板安装、PCB板安装等多种类型，满足不同设备的装配需求。

　　Classified by installation method: There are various types such as panel installation, PCB board installation, etc., to meet the assembly needs of different devices.

　　4.按材质和外观分类：包括塑料外壳、金属外壳，以及带指示灯、不带指示灯等多种款式，以适应不同的审美和功能需求。

　　Classified by material and appearance: including plastic shells, metal shells, as well as various styles with and without indicator lights to meet different aesthetic and functional needs.
