The **W2PA-52Y-R2/N** is a specific electronic component typically identified as a **Miniature Toggle Switch** or a specialized switch assembly. Below is a detailed technical breakdown of its electronic parts and specifications. --- ### 1. General Specifications This component is designed for low-power signal switching or panel control in industrial and consumer electronics. | Parameter | Specification | | :--- | :--- | | **Component Type** | Toggle Switch (Miniature) | | **Switch Configuration** | DPDT (Double Pole Double Throw) | | **Contact Rating** | 2A @ 250VAC / 5A @ 125VAC | | **Terminal Type** | Right Angle PC Pin (Through-Hole) | | **Operating Force** | 4.90N to 14.7N (Standard range) | | **Mechanical Life** | 50,000 ~ 100,000 Cycles | --- ### 2. Internal Electronic Parts and Materials The performance of the W2PA series depends on the quality of its internal metallurgy and housing materials: #### A. Contacts (The Conductive Path) * **Material:** Often Gold-over-Silver or Silver-plated copper. * **Function:** Ensures low contact resistance (usually < 10mΩ) to prevent signal loss or heating during current flow. #### B. The Actuator (Toggle Lever) * **Material:** Chrome-plated brass or stainless steel. * **Function:** Provides the mechanical interface for the user. In the "R2" variant, the lever length and shape are standardized for ergonomic toggle action. #### C. Housing and Base * **Material:** Diallyl Phthalate (DAP) or High-temp Nylon (UL94V-0). * **Function:** Provides electrical insulation between terminals and high heat resistance during the soldering process. #### D. Terminals * **Design:** The "/N" suffix usually denotes a specific terminal finish or lead-free (RoHS) compliance. * **Orientation:** Right-angle pins allow the switch to be mounted on a vertical PCB while the toggle protrudes through a front panel. --- ### 3. Circuit Logic (DPDT) The "52" in the part number sequence often refers to the switching function. A DPDT configuration allows for the following circuit control: ```mermaid Terminal 1 --- Terminal 2 (Common) --- Terminal 3 Terminal 4 --- Terminal 5 (Common) --- Terminal 6 ``` * **Position 1:** Common pins (2 & 5) are connected to pins 1 & 4. * **Position 2:** Common pins (2 & 5) are connected to pins 3 & 6. --- ### 4. Application Use Cases 1. **Telecommunications:** Routing audio or data signals. 2. **Instrumentation:** Power ON/OFF or Mode selection for multimeters and oscilloscopes. 3. **Medical Equipment:** Interface controls for diagnostic handhelds. ---
