The **W2TG0-2C2-R2/CE** is a specialized industrial push-button switch, typically part of the **IDEC TW Series** (specifically the 22mm heavy-duty line). These components are designed for harsh environments, providing tactile feedback and reliable electrical switching for control panels. ### 1. General Specifications Below is a breakdown of the core technical parameters for this specific model: | Feature | Specification | | :--- | :--- | | **Series** | IDEC TW Series (Heavy Duty) | | **Mounting Hole Size** | 22mm (standard industrial diameter) | | **Operator Type** | Round Flush Push-button | | **Contact Configuration** | 2C (2PDT or 2NO/2NC depending on module) | | **Function** | Momentary (Non-locking) | | **Termination** | Screw Terminals with M3.5 screws | | **Degree of Protection** | IP65 (Water and Dust tight) | --- ### 2. Detailed Electronic & Mechanical Parts #### A. Contact Block (The Switching Mechanism) The "2C" in the part number indicates the contact arrangement. * **Double Pole:** It controls two separate electrical circuits simultaneously. * **High Conductivity:** The contacts are usually made of silver (Ag) or gold-flashed silver to minimize electrical resistance and prevent oxidation. * **Voltage/Current Rating:** Typically rated for **10A** thermal current ($I_{th}$), with operational voltages ranging from **24V DC to 600V AC**. #### B. The Operator (The Physical Interface) * **Bezel Material:** Usually chrome-plated zinc or high-impact plastic (indicated by the suffix). * **Action:** The **Momentary** action means the switch returns to its original position as soon as the finger is removed. * **Return Spring:** A high-tension stainless steel spring ensures crisp tactile feedback and millions of operations (typically rated for 5 million mechanical cycles). #### C. Environmental Protections (CE & R2) * **R2 Suffix:** Often refers to a specific color code (Red) or a specific revision of the guard/bezel design. * **CE Marking:** Confirms the part meets European Union safety, health, and environmental protection requirements. * **Gasket:** Includes an oil-resistant rubber gasket to prevent liquid ingress into the control box. --- ### 3. Typical Application Schematic In a control circuit, this part is used as a **Start** or **Signal** button. ```mermaid graph LR A[Power Source] --> B{W2TG0-2C2-R2/CE} B -- Contact 1 --> C[Motor Starter/PLC Input] B -- Contact 2 --> D[Status Indicator Light] ``` --- ### 4. Mounting & Connection The device uses a **locking ring system**. To install: 1. Insert the operator through the 22mm hole from the front. 2. Tighten the locking nut from the rear. 3. Snap the contact blocks onto the back of the operator. 4. Wire the screw terminals (compatible with ring or fork lugs).
