The **W2SP-1B3-R2/N** is a specific electronic component belonging to the **Waterproof Micro Switch** family, commonly manufactured by companies like **ZIPPY** or similar industrial switch specialists. These switches are designed for durability in harsh environments. --- ### 1. Technical Specifications The part number is a coded string representing its physical and electrical characteristics: | Feature | Specification | | :--- | :--- | | **Switch Type** | Micro Switch (Snap Action) | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 0.1A to 3A (depending on voltage) | | **Environmental Protection** | IP67 (Dust-tight and Waterproof) | | **Operating Force** | Medium (approx. 150gf - 200gf) | | **Terminal Type** | Solder or Wire Lead (depending on suffix) | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly by brand, the code generally breaks down as follows: * **W2:** Series identifier (usually denotes the waterproof sub-miniature series). * **SP:** Standard Pressure/Operating force. * **1B3:** Contact material and rating code (Gold plated contacts are common in this series for low-current signal switching). * **R2:** Lever type. "R" usually refers to a **Roller Lever**, and "2" indicates the length or offset of the lever. * **N:** Termination/Housing variant (often denotes a specific mounting hole size or wire orientation). --- ### 3. Key Electronic Features * **Snap Action Mechanism:** Uses a spring-loaded mechanism to flip contacts rapidly, ensuring a clean electrical break and minimizing arcing. * **Sealed Construction:** The "W" in the prefix indicates a silicone or rubber boot seal, preventing moisture, oil, and dust from entering the internal contact chamber. * **Long Life Cycle:** These parts are usually rated for 100,000 to 1,000,000 mechanical operations. --- ### 4. Common Applications Due to its waterproof nature, this part is used in: 1. **Automotive:** Door latches, seatbelt sensors, and hood detection. 2. **Home Appliances:** Washing machines (lid locks) and refrigerators. 3. **Industrial:** Limit switches for CNC machinery or outdoor gates. ---
