## Overview of the JR-11-R The **JR-11-R** typically refers to a specific model of an **IEC C14 Power Inlet with an integrated Rocker Switch**. This component is widely used in electronic devices to manage power input and provide a manual ON/OFF mechanism. --- ### 1. Key Components & Features The JR-11-R is a composite electronic part consisting of three primary sections integrated into a single housing: | Feature | Description | | :--- | :--- | | **Connector Type** | IEC 60320 C14 (Male) | | **Switch Type** | 2-Position Rocker Switch (SPST or DPST) | | **Mounting Style** | Snap-in or Screw Mount (Panel Mount) | | **Illumination** | Often features a built-in Neon or LED indicator (depending on variant) | | **Terminals** | 4.8mm or 6.3mm Quick-connect / Solder tabs | --- ### 2. Technical Specifications Below are the standard electrical and physical parameters for the JR-11-R series: * **Rated Voltage:** 250V AC * **Rated Current:** 10A (UL/VDE standards) * **Contact Resistance:** ≤ 50mΩ * **Insulation Resistance:** ≥ 100MΩ (500V DC) * **Dielectric Strength:** 2000V AC / 1 minute * **Operating Temperature:** -25°C to +85°C * **Material:** Thermoplastic (UL 94V-0 flammability rating) --- ### 3. Wiring Configuration The back of the JR-11-R features several metal pins. Proper wiring is essential for safety: 1. **Input Pins (C14):** Three pins representing **Line (L)**, **Neutral (N)**, and **Ground (E)**. 2. **Switch Pins:** Two or four pins that interrupt the Line (and sometimes Neutral) path before sending power to the internal circuit. 3. **Grounding:** The Earth pin is usually connected directly to the chassis of the device for safety. --- ### 4. Common Applications Because it combines an inlet and a switch, the JR-11-R saves space on the back panels of: * 3D Printers (e.g., Ender series) * Desktop Power Supplies * Lab Equipment * Audio/Video Amplifiers * Industrial Control Boxes --- ### 5. Safety Considerations > [!WARNING] > **High Voltage Hazard:** When working with the JR-11-R, ensure the device is unplugged. Improper wiring of the Rocker Switch can cause a short circuit or fire. Always verify if your specific "R" version includes an internal fuse holder, as some variants (like the JR-11-F-R) include a 5x20mm fuse slot for added protection.
