The **JR-01-R** is a standard electronic component typically identified as a **Power Entry Module** or a **C14 AC Power Socket** with an integrated rocker switch. These parts are commonly found in power supplies, 3D printers, and industrial machinery to manage the connection between the main AC power cord and the internal circuitry. ### 1. Key Electronic Specifications Most variations of the JR-01-R share the following technical parameters: | Parameter | Typical Rating | | :--- | :--- | | **Connector Type** | IEC 320 C14 (Male) | | **Voltage Rating** | 250V AC | | **Current Rating** | 10A (International) / 15A (UL/North America) | | **Switch Type** | 2-Position (ON-OFF) Rocker Switch | | **Dielectric Strength** | > 2000V AC / 1 minute | | **Mounting Style** | Snap-in or Screw-mount (depending on sub-model) | --- ### 2. Physical Components The JR-01-R is an assembly consisting of three primary functional parts: 1. **C14 Inlet:** The standard three-prong interface that accepts a standard PC power cable (C13 connector). 2. **Rocker Switch:** A red or black SPST (Single Pole Single Throw) or DPST (Double Pole Single Throw) switch that controls the live/neutral lines. 3. **Terminals:** Usually 4.8mm or 6.3mm quick-connect spade terminals (fastons) located on the rear for internal wiring. --- ### 3. Pinout and Wiring Logic Wiring a JR-01-R correctly is critical for safety. The back of the module usually follows this logic: * **L (Live):** Connected to the switch to break the circuit when turned off. * **N (Neutral):** Connected to the load (often routed through the switch in DPST versions). * **E (Earth/Ground):** Connected directly to the metal chassis of the device for safety. --- ### 4. Common Applications * **DIY Electronics:** Enclosures for hobbyist projects (e.g., CNC controllers). * **Office Equipment:** Laser printers and desktop computers. * **Audio Gear:** Amplifiers and active speakers. * **Laboratory Tools:** Centrifuges, ovens, and power supply units.
