贴片带灯拨动开关 SMD
贴片带灯拨动开关 SMD 是一种表面贴装（SMT）拨动开关，其内置发光二极管 (LED) 指示灯。它们专为在印刷电路板 (PCB) 上使用而设计，可提供视觉指示以指示开关状态。
工作原理
贴片带灯拨动开关 SMD 由以下组件组成：
**触点：**有三个或四个触点，排列成一排。
**极：**有两个或三个极，每个极连接到一个触点。
**拨杆：**拨杆是一个可移动的元件，用于连接触点。
**LED：**LED 指示灯位于拨杆下方，当开关接通时会亮起。
当拨杆移动到一个方向时，它会连接第一个触点和第二个触点（或第一个触点和第二个触点和第三个触点），同时断开第一个触点和第三个触点（或第一个触点和第四个触点）。 LED 指示灯也会亮起，指示开关处于接通状态。当拨杆移动到另一个方向时，触点断开，LED 指示灯熄灭，指示开关处于断开状态。
类型
有许多不同类型的贴片带灯拨动开关 SMD，包括：
**单刀双掷 (SPDT)：**最基本的类型，具有一个输入和两个输出，以及一个 LED 指示灯。
**双刀双掷 (DPDT)：**具有两个输入和两个输出，以及一个 LED 指示灯。
**三刀双掷 (3PDT)：**具有三个输入和两个输出，以及一个 LED 指示灯。
**四刀双掷 (4PDT)：**具有四个输入和两个输出，以及一个 LED 指示灯。
优点
贴片带灯拨动开关 SMD 具有以下优点：
**尺寸小巧：**它们非常小巧，非常适合空间受限的应用。
**易于组装：**它们可以轻松地使用 SMT 设备组装到 PCB 上。
**可靠性：**它们非常可靠，可以承受恶劣的环境条件。
**低功耗：**它们功耗低，非常适合电池供电设备。
**视觉指示：**LED 指示灯提供清晰的视觉指示，指示开关状态。
应用
贴片带灯拨动开关 SMD 广泛用于各种应用中，例如：
**消费电子产品：**智能手机、平板电脑、可穿戴设备
**工业控制：**控制面板、人机界面
**医疗设备：**监护仪、输液泵
**汽车：**仪表板开关、控制台开关
**家用电器：**洗衣机、烘干机

SMD strip light toggle switch
SMD strip light toggle switch is a surface mount (SMT) toggle switch with built-in light-emitting diode (LED) indicator lights. They are designed specifically for use on printed circuit boards (PCBs) and can provide visual indications to indicate switch status.
working principle
The SMD strip light toggle switch consists of the following components:
**Contact: * * There are three or four contacts arranged in a row.
**Pole: * * There are two or three poles, each connected to a contact.
**Pulling rod: * * Pulling rod is a movable component used to connect contacts.
**LED: The LED indicator light is located below the lever and will light up when the switch is turned on.
When the lever moves in one direction, it connects the first and second contacts (or the first and second contacts and the third contact), while disconnecting the first and third contacts (or the first and fourth contacts). The LED indicator light will also light up, indicating that the switch is in the on state. When the lever moves in another direction, the contact opens, the LED indicator light goes out, and the indicator switch is in the disconnected state.
type
There are many different types of SMD strip light toggle switches, including:
**Single pole double throw (SPDT): * * The most basic type, with one input and two outputs, as well as an LED indicator light.
**Double Knife Double Throw (DPDT): * * has two inputs and two outputs, as well as an LED indicator light.
**Three pole double throw (3PDT): * * has three inputs and two outputs, as well as an LED indicator light.
**Four pole double throw (4PDT): * * has four inputs and two outputs, as well as an LED indicator light.
advantage
SMD strip light toggle switch has the following advantages:
**Compact size: * * They are very compact and suitable for applications with limited space.
**Easy to assemble: * * They can be easily assembled onto PCBs using SMT equipment.
**Reliability: * * They are very reliable and can withstand harsh environmental conditions.
**Low power consumption: * * They have low power consumption and are very suitable for battery powered devices.
**Visual indication: * * LED indicator lights provide clear visual indication of switch status.
application
SMD strip light toggle switch is widely used in various applications, such as:
**Consumer electronics products: * * smartphones, tablets, wearable devices
**Industrial control: * * Control panel, human-machine interface
**Medical equipment: * * monitor, infusion pump
**Car: * * Instrument panel switch, console switch
**Household appliances: * * washing machine, dryer
