贴片带灯开关
贴片带灯开关是一种轻触开关，采用表面贴装技术（SMT）安装在印刷电路板上（PCB）。它具有一个内置的LED灯，当开关处于打开或关闭状态时，该LED灯会亮起。
结构和工作原理
贴片带灯开关的结构非常简单，主要由以下组件组成：
**开关触点：**两个金属触点，当开关按压时闭合，释放时断开。
**LED灯：**一个小型的发光二极管（LED），当电流通过时亮起。
**电阻器：**一个电阻器与LED串联，以限制通过LED的电流。
当开关按压时，触点闭合，电流通过LED和电阻器，导致LED亮起。当开关释放时，触点断开，LED熄灭。
优点
贴片带灯开关具有以下优点：
**紧凑尺寸：**由于采用SMT安装，贴片带灯开关非常紧凑，非常适合空间受限的应用。
**易于安装：**可以轻松地使用回流焊或波峰焊工艺将贴片带灯开关安装到PCB上。
**可靠性高：**贴片带灯开关具有很高的可靠性，因为它们没有活动部件（例如杠杆或按钮）。
**美观：**内置的LED灯可以发出各种颜色的光，这可以增强PCB的外观。
应用
贴片带灯开关主要用于以下应用：
便携式电子设备（例如智能手机、平板电脑和笔记本电脑）的开关
家用电器（例如微波炉、烤面包机和咖啡机）的开关
工业设备（例如PLC和传感器）的开关
汽车和航空航天应用
选择
选择贴片带灯开关时，应考虑以下因素：
所需的开关类型（常开或常闭）
电流和电压额定值
LED灯的颜色
尺寸和封装类型
安装
贴片带灯开关的安装通常使用回流焊或波峰焊工艺。制造商的说明应始终遵循以确保正确安装。

SMT strip light switch
Surface mount with light switch is a type of tactile switch that is mounted on a printed circuit board (PCB) using surface mount technology (SMT). It has a built-in LED light that lights up when the switch is in the on or off state.
Structure and working principle
The structure of the patch with light switch is very simple, mainly composed of the following components:
**Switch contacts: * * Two metal contacts that close when the switch is pressed and open when released.
**LED light: * * A small light-emitting diode (LED) that lights up when current passes through.
**Resistors: * * A resistor is connected in series with the LED to limit the current passing through the LED.
When the switch is pressed, the contacts close and current flows through the LED and resistor, causing the LED to light up. When the switch is released, the contacts open and the LED goes out.
advantage
The patch strip light switch has the following advantages:
**Compact size: * * Due to the use of SMT installation, the surface mount with light switch is very compact and suitable for space limited applications.
**Easy to install: * * SMT strip light switches can be easily installed onto PCBs using reflow soldering or wave soldering techniques.
**High reliability: * * Surface mount light switches have high reliability because they do not have moving parts (such as levers or buttons).
**Aesthetic: The built-in LED lights can emit light of various colors, which can enhance the appearance of the PCB.
application
SMT strip light switch is mainly used for the following applications:
Switches for portable electronic devices such as smartphones, tablets, and laptops
Switches for household appliances such as microwave ovens, toasters, and coffee makers
Switches for industrial equipment such as PLCs and sensors
Automotive and Aerospace Applications
choice
When choosing a patch with light switch, the following factors should be considered:
Required switch type (normally open or normally closed)
Rated values of current and voltage
Color of LED lights
Size and packaging type
install
The installation of surface mount strip switches usually uses reflow soldering or wave soldering processes. The manufacturer's instructions should always be followed to ensure proper installation.
