自锁带灯按键开关技术介绍
自锁带灯按键开关是一种具有内置发光二极管 (LED) 指示灯的按键开关，当按下时保持接通状态。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
自锁带灯按键开关由以下组件组成：
**触点：**有两个触点，一个常开 (NO) 触点和一个常闭 (NC) 触点。
**极：**有两个极，一个连接到 NO 触点，另一个连接到 NC 触点。
**按钮：**一个可移动的按钮，用于操作开关。
**LED：**LED 指示灯位于按钮下方，当开关接通时会亮起。
当按钮按下时，NO 触点和极连接，NC 触点和极断开。 LED 指示灯也会亮起，指示开关处于接通状态。当按钮松开时，开关保持接通状态，直到再次按下按钮。
类型
有许多不同类型的自锁带灯按键开关，包括：
**单极单掷 (SPST)：**最基本的类型，具有一个 NO 触点和一个 NC 触点，以及一个 LED 指示灯。
**双极单掷 (DPST)：**具有两个 NO 触点和两个 NC 触点，以及一个 LED 指示灯。
优点
自锁带灯按键开关具有以下优点：
**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。
**自锁功能：**当按下时保持接通状态，这对于需要保持开关接通状态的应用非常有用。
应用
自锁带灯按键开关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

Introduction to self-locking button switch technology with lights
The self-locking strip light button switch is a button switch with a built-in light emitting diode (LED) indicator light, which remains on when pressed. They are designed specifically for use on printed circuit boards (PCBs) and can provide visual indications to indicate switch status.
working principle
The self-locking strip light button switch consists of the following components:
**Contact: * * There are two contacts, one normally open (NO) contact and one normally closed (NC) contact.
**Pole: * * There are two poles, one connected to the NO contact and the other connected to the NC contact.
**Button: * * A movable button used to operate switches.
**LED: The LED indicator light is located below the button and will light up when the switch is turned on.
When the button is pressed, the NO contact and pole are connected, and the NC contact and pole are disconnected. The LED indicator light will also light up, indicating that the switch is in the on state. When the button is released, the switch remains on until the button is pressed again.
type
There are many different types of self-locking button switches with lights, including:
**Single pole single throw (SPST): * * The most basic type, with one NO contact and one NC contact, as well as an LED indicator light.
**Bipolar Single Throw (DPST): * * has two NO contacts and two NC contacts, as well as an LED indicator light.
advantage
The self-locking button switch with light 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.
**Self locking function: * * When pressed, it remains connected, which is very useful for applications that require keeping the switch connected.
application
Self locking button switches with lights are 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
