The **38-RRA15C112S** is a part number typically associated with the **RRA Series** of power rocker switches manufactured by **Carling Technologies** (or similar electronic component distributors). Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications This component is a sub-miniature, single-pole rocker switch designed for high-current applications in a compact form factor. | Feature | Specification | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuitry** | SPST (Single Pole Single Throw) | | **Switch Function** | ON-OFF | | **Current Rating** | 10A 125VAC / 6A 250VAC | | **Mounting Type** | Snap-in Panel Mount | | **Termination** | .187" (4.8mm) Quick Connect Tabs | --- ### 2. Part Number Breakdown While manufacturer prefixes can vary, the suffixing for this series generally follows this logic: * **38-RRA**: Identifies the Series (RRA High-Inrush Rocker). * **15C**: Likely refers to the electrical rating or the actuator style (curved rocker). * **112**: Internal code for color and marking (often indicates a Black body with Black rocker). * **S**: Typically denotes the contact material or a specific solder/quick-connect terminal style. --- ### 3. Key Electronic Characteristics #### High Inrush Capability The RRA series is specifically engineered to handle high inrush currents. This makes it suitable for power supplies or motors where the initial surge of electricity is significantly higher than the steady-state operating current. #### Durability & Standards * **Electrical Life:** Usually rated for 10,000 to 50,000 cycles depending on the load. * **Dielectric Strength:** Often 1,500V RMS (minimum). * **Insulation Resistance:** 100 Megaohms (minimum). * **Certifications:** Typically UL, CSA, and VDE recognized. --- ### 4. Physical Dimensions These switches are favored for "space-constrained" designs. * **Panel Cutout:** Approximately 13.0mm x 19.2mm (standard mini-rocker size). * **Actuator:** Non-illuminated (based on this specific part number). --- ### 5. Common Applications * **Power Supplies:** Main power toggle for desktop or industrial units. * **Appliances:** Vacuum cleaners, coffee makers, and kitchen electronics. * **Audio/Visual:** Professional amplifiers and mixing consoles. * **Computers:** Peripheral power control.
