The **V-2B6-R** is a specific model of high-performance **Micro Switch** (often categorized as a snap-action switch), typically manufactured by **Omron**. These switches are designed for reliability and are used in everything from industrial machinery to household appliances. --- ### 1. Technical Specifications Table | Parameter | Specification Details | | :--- | :--- | | **Switch Type** | Miniature Snap Action / Micro Switch | | **Actuator Style** | Pin Plunger (Basic) | | **Contact Form** | SPST-NC (Single Pole Single Throw, Normally Closed) | | **Current Rating** | 15A to 20A (Heavy Duty) | | **Voltage Rating** | 250 VAC | | **Termination Style** | Solder / Quick Connect (#187) | | **Operating Force** | ~1.96 N (200 gf) | --- ### 2. Breakdown of the Model Name (V-2B6-R) Electronic part numbers are often codes representing specific physical and electrical traits. Here is the breakdown for this series: * **V:** Refers to the "V-Series" miniature basic switches known for high durability and a wide range of current capacities. * **2:** Usually indicates the specific contact gap or a variation in the internal mechanism. * **B:** Generally signifies the **terminal type** (in this case, Solder terminals or #187 tab terminals). * **6:** Relates to the **Contact Form**. In this specific sequence, it typically denotes a **Normally Closed (NC)** configuration. * **R:** Often indicates a specific mounting orientation or a "Right-hand" side configuration, though in some Omron series, it may refer to the material or specialized certifications. --- ### 3. Key Electronic Components & Materials The "electronic parts" within this switch consist of the following: 1. **Contacts:** Usually made of **Silver Alloy**. This material is chosen for its excellent conductivity and resistance to "pitting" or "welding" under high electrical loads. 2. **Spring Mechanism:** A high-precision **Beryllium Copper** or Stainless Steel snap spring. This ensures the "snap" action happens instantly, minimizing electrical arcing. 3. **Housing:** Made of **Thermoplastic (PBT)** or Phenolic resin. These materials are heat resistant and provide high dielectric strength (insulation). 4. **Terminals:** Brass with silver plating to ensure low contact resistance and ease of soldering. --- ### 4. Applications Because of its high current rating (15A+), the V-2B6-R is commonly found in: * **Safety Interlocks:** Microwave doors or industrial cage doors. * **Control Panels:** As a limit switch to detect the position of moving parts. * **Appliances:** Vacuum cleaners, heaters, and water pumps.
