The **RGSCB901-R-B-B-0** is a specific part number for a high-quality rocker switch manufactured by **Carling Technologies**. It belongs to the **R-Series** Curvette line, known for its versatility and durability in small appliances and industrial equipment. ### 1. Technical Specifications Breakdown The part number follows a specific nomenclature that defines its electronic and physical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Series** | RGSC | R-Series Curvette Double Pole Switch | | **Circuitry** | B | Single Pole Single Throw (SPST) | | **Rating** | 901 | 15A 125VAC; 10A 250VAC; 3/4 HP 125-250VAC | | **Illumination** | R | Non-Illuminated (standard) | | **Actuator Color** | B | Black | | **Bezel Color** | B | Black | | **Marking** | 0 | No legend/marking on the face | --- ### 2. Key Electronic Components & Materials This switch is designed to handle significant current loads despite its compact size. The internal "electronic" architecture consists of: * **Contacts:** Typically made of silver alloy (Silver Cadmium Oxide) to resist "arcing" and welding under high inductive loads (like motors). * **Terminals:** .250-inch (6.35mm) Quick-Connect tabs. These are tin-plated brass, designed for low resistance and high conductivity. * **Mechanism:** A "patented" self-cleaning wiping contact design. Every time the switch is flipped, the internal contacts rub against each other slightly, clearing away oxidation and carbon buildup. * **Housing:** Nylon 66 (UL 94V-2 rated), which provides excellent electrical insulation and heat resistance. --- ### 3. Usage Context Due to its **3/4 HP (Horsepower)** rating, this switch is not just for turning on lights; it is rugged enough to handle the "inrush current" of electric motors. #### Common Applications: * **Power Supplies:** Main On/Off switch for desktop hardware. * **Appliances:** Vacuum cleaners, coffee makers, and food processors. * **Industrial:** Control panels for HVAC or small machinery. --- ### 4.
