The **W2PV-C2S21-R** is a specific electronic component typically categorized under **Pushbutton Switches** or **Industrial Control Units**, often associated with manufacturers like OMRON or specialized industrial switch providers. It is designed for panel mounting in control circuits. --- ### Technical Specifications Below are the primary electronic and mechanical characteristics for this series: | Property | Description | | :--- | :--- | | **Component Type** | Illuminated Pushbutton Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) or DPST (Double Pole Single Throw) | | **Switch Action** | Momentary (Spring Return) | | **Illumination Source** | Integrated LED | | **Voltage Rating** | 24V AC/DC (Standard for LEDs) | | **Current Rating** | Typically 1A to 5A (depending on load type) | | **Mounting Diameter** | 22mm (Industrial Standard) | --- ### Key Features 1. **Modular Construction**: The unit is generally composed of three detachable parts: the **Operator** (the button itself), the **Lamp Module** (LED driver), and the **Contact Block** (the electronic switching mechanism). 2. **LED Illumination**: The "21-R" suffix often indicates a **Red LED** configuration. This provides visual feedback to the operator, signaling power status or alarm conditions. 3. **Environmental Protection**: These parts are usually rated **IP65 or IP66**, meaning they are protected against dust and low-pressure water jets, making them suitable for harsh industrial environments. --- ### Internal Electronic Operation The device functions as a physical bridge in a circuit: * **Input (Terminals 1-2):** Connects the load. When the button is pressed, the internal copper contacts bridge the gap, allowing current to flow. * **LED Terminals (X1-X2):** These are powered independently or in parallel with the switch to provide the backlight. The LED includes an internal resistor to handle the specified voltage (24V). --- ### Typical Applications * **Control Panels**: Used as a start/stop button for motors. * **Emergency Signaling**: The red illumination is frequently used for warning indicators. * **Industrial Automation**: Interfacing with PLCs (Programmable Logic Controllers) to trigger logic sequences.
