The **WMS2-6B-R** is a specific electronic component typically categorized under **Slide Switches** (specifically miniature or sub-miniature types). These are commonly used in telecommunications, consumer electronics, and industrial controls. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Slide Switch | | **Configuration** | DPDT (Double Pole Double Throw) | | **Mounting Type** | Right Angle, Through-Hole (PCB) | | **Number of Positions** | 2-Position (On-On) | | **Terminal Type** | PC Pin | ### 2. Electrical Characteristics These parts are designed for low-power signal switching rather than high-current power applications. * **Contact Rating:** Usually rated for **0.4 VA max** at **20V AC or DC**. * **Contact Resistance:** Typically less than **20 mΩ** (initial). * **Insulation Resistance:** Minimum of **1,000 MΩ** at 500V DC. * **Dielectric Strength:** 1,000 V RMS at sea level. * **Mechanical Life:** Generally rated for **30,000 to 50,000 make-and-break cycles**. ### 3. Physical & Material Composition The "R" suffix often indicates compliance with environmental standards or specific packaging (like RoHS compliance). * **Housing:** High-temperature plastic (often UL94V-0 rated). * **Actuator:** Thermoplastic or metal, depending on the specific series variation. * **Contacts:** Gold over nickel plating (common for low-level logic switching to prevent oxidation). * **Seal:** Many versions feature an epoxy terminal seal to prevent contamination during soldering. ### 4. Pinout and Circuitry (DPDT) The **DPDT** configuration means the switch controls two separate circuits simultaneously. Each "pole" has one common terminal and two "throw" terminals. ```text Circuit Diagram: Pole 1: [Terminal 1] --- [Common A] --- [Terminal 2] Pole 2: [Terminal 3] --- [Common B] --- [Terminal 4] ``` ### 5. Common Applications * **Handheld devices:** Power on/off or mode selection. * **Instrumentation:** Selecting between different sensor inputs. * **Networking:** Reset switches or configuration toggles on routers. * **Medical Electronics:** Low-power signal routing. ---
