The part number **R13-R** (often associated with the **R13 series**) typically refers to a standard line of **Panel Mount Rocker Switches**. These are widely used in consumer electronics, automotive accessories, and industrial panels to control power flow. --- ### 1. General Specifications While the specific suffix after "R" can denote color or circuitry, the R13-R series generally shares these physical and electrical characteristics: | Feature | Typical Specification | | :--- | :--- | | **Mounting Type** | Snap-in Panel Mount | | **Hole Diameter** | Usually 20mm (Round) or 12mm depending on sub-model | | **Current Rating** | 6A to 16A at 125VAC/250VAC | | **Contact Resistance** | < 50mΩ | | **Insulation Resistance** | > 100MΩ (500VDC) | | **Operating Life** | 10,000+ Cycles | --- ### 2. Common Configurations The "R" in the series often implies a **Round** body style. These switches come in several functional variations: * **SPST (Single Pole Single Throw):** A simple On/Off switch with two terminals. * **SPDT (Single Pole Double Throw):** An On/On or On/Off/On switch with three terminals. * **Illuminated vs. Non-Illuminated:** * Models with an internal LED or Neon lamp require a third "ground" pin to power the light. * Standard models are purely mechanical. --- ### 3. Pinout and Connection For a standard 3-pin illuminated R13-R rocker switch, the wiring is usually structured as follows: ```text Pin 1 (Gold/Brass): Ground (for the internal light) Pin 2 (Middle): Load (to the device being powered) Pin 3 (Silver): Power (from the battery or source) ``` --- ### 4. Applications * **Automotive:** Dash switches for lights, fans, or winches. * **Power Strips:** Used as the main reset/power toggle. * **DIY Projects:** Ideal for Arduino/Raspberry Pi enclosures due to the easy-to-drill round hole. * **Appliances:** Vacuum cleaners, coffee makers, and power tools. ---
