The **W2PV-C2S11-R2** is a specific part number belonging to the **W2PV Series** of industrial push-button switches, typically manufactured by companies like **Omron** or similar industrial control providers. This component is designed for control panels, machinery, and automation systems. --- ### 1. Part Number Breakdown (Technical Specifications) While naming conventions can vary slightly by manufacturer, the code typically breaks down as follows: | Component Code | Specification Detail | Description | | :--- | :--- | :--- | | **W2PV** | Series | Round industrial push-button/pilot light series | | **C2** | Housing Type | Usually refers to the bezel material (e.g., Plastic or Metal) | | **S** | Operation | Non-lighted, momentary action (Spring return) | | **11** | Contact Configuration | 1NO + 1NC (One Normally Open + One Normally Closed) | | **R** | Color | **Red** button cap | | **2** | Voltage/Mounting | Typically refers to the mounting hole size (e.g., 22mm) | --- ### 2. Key Electronic Components The assembly consists of three primary functional modules: #### A. The Operator (Actuator) The visible part on the panel. In this model, it is a **Red Flush Button**. It is "Momentary," meaning it only stays active while your finger is pressing it; it springs back once released. #### B. The Switch Block (Contact Block) This is the electronic "heart" of the device. * **1NO (Normally Open):** Completes the circuit when the button is pressed (Start function). * **1NC (Normally Closed):** Breaks the circuit when the button is pressed (Stop function). * **Ratings:** Usually rated for **AC-15** (inductive loads) or **DC-13** (solenoids), typically handling up to 10A at 120V or 3A at 240V. #### C. The Mounting Collar The mechanical bridge that locks the operator to the contact blocks through the panel hole (22mm diameter). --- ### 3. Electrical Characteristics | Parameter | Standard Value | | :--- | :--- | | **Mounting Diameter** | 22.3 mm | | **Insulation Resistance** | 100 MΩ minimum | | **Dielectric Strength** | 2,500 VAC, 50/60 Hz for 1 min | | **Mechanical Life** | ~500,000 operations | | **Electrical Life** | ~100,000 operations (under load) | | **IP Rating** | IP65 or IP66 (Oil-tight and Water-resistant) | --- ### 4.
