功能键/按钮

繁體:功能鍵/按鈕

功能键和按钮是集成在人机界面(HMI)面板中的机电式或薄膜式输入组件,用于为操作员提供对特定机器功能、模式或序列的直接触觉控制。

技术定义与适配语境
典型 功能键/按钮 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

功能键和按钮是集成在人机界面(HMI)面板中的机电式或薄膜式输入组件,旨在为操作员提供对工业自动化系统中特定机器功能、模式或序列的直接触觉控制。它们作为启动命令、导航菜单、调整参数以及触发紧急停止或安全协议的主要物理接口。 它们通过在被按下时闭合电路来工作。此动作向HMI的控制器或PLC(可编程逻辑控制器)发送一个离散的数字信号(例如电压变化或触点闭合)。控制器根据其编程逻辑解释该信号以执行相关命令,例如启动过程、更改操作模式或调用显示器上的特定屏幕。

定义
功能键和按钮是集成在人机界面(HMI)面板中的机电式或薄膜式输入组件,旨在为操作员提供对工业自动化系统中特定机器功能、模式或序列的直接触觉控制。它们作为启动命令、导航菜单、调整参数以及触发紧急停止或安全协议的主要物理接口。

它们通过在被按下时闭合电路来工作。此动作向HMI的控制器或PLC(可编程逻辑控制器)发送一个离散的数字信号(例如电压变化或触点闭合)。控制器根据其编程逻辑解释该信号以执行相关命令,例如启动过程、更改操作模式或调用显示器上的特定屏幕。
工作原理
They operate by completing an electrical circuit when actuated (pressed). This action sends a discrete digital signal (e.g., a voltage change or contact closure) to the HMI's controller or PLC (Programmable Logic Controller). The controller interprets this signal according to its programmed logic to execute the associated command, such as starting a process, changing an operating mode, or calling up a specific screen on the display.
材料
键帽/按钮表面:ABS塑料、聚碳酸酯或硅胶(通常带有激光蚀刻或模制标识)。接触机构:镀金或银合金触点(用于机电式)导电硅胶垫(用于薄膜式)。外壳/底座:聚碳酸酯、ABS或金属(恶劣环境下使用不锈钢)。密封件:硅胶或橡胶垫圈用于IP防护等级版本。
IP Rating
IP65, IP67, or IP69K common for industrial use
Lifecycle

FMEA · 风险与缓解

诱因 → 失效模式 → 工程缓解

Contaminant ingress due to damaged seal or improper installation.->Button becomes unresponsive or triggers false signals, halting production.->Use IP-rated buttons suitable for the environment; implement regular inspection of seals; ensure proper panel cutouts and mounting torque.
Mechanical wear from excessive actuation force or misalignment.->Keycap breaks or contact mechanism fails, requiring replacement.->Select buttons with lifecycle ratings exceeding expected use; design panels to prevent off-center pressing; train operators on proper use.
Electrical overload or incorrect voltage application.->Internal contacts weld or burn out, causing permanent activation or open circuit.->Ensure power supply matches button rating (typically 24V DC); incorporate fusing or current limiting in circuit design.

常见问题

What is the difference between a function key and an emergency stop button on an HMI?

A function key is a general-purpose input for routine operations (start, stop, mode select). An emergency stop (e-stop) button is a safety-critical component with a distinct, latching mushroom head design that, when pressed, immediately halts machine motion by breaking the safety circuit, as mandated by standards like ISO 13850. It requires a manual twist or pull to reset.

How are HMI buttons sealed for harsh environments?

They use silicone or rubber gaskets behind the panel and often feature a sealed plunger design to achieve IP65, IP67, or IP69K ratings, protecting against dust, water jets, and high-pressure washdowns common in food, chemical, or pharmaceutical manufacturing.
