The **JR-1B-R** is a specific part number primarily associated with **power entry modules** or **rocker switches** produced by manufacturers like **Canal Components** or **Zippy Technology**. It is most commonly found in computer power supplies, industrial machinery, and consumer electronics. Below is a detailed breakdown of its electronic specifications and characteristics. ### 1. General Specifications The JR-1B-R is typically a non-illuminated, single-pole single-throw (SPST) or single-pole double-throw (SPDT) rocker switch integrated into a power socket. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Rocker Switch / Power Entry Module | | **Rating (AC)** | 10A 250V AC / 15A 125V AC | | **Contact Resistance** | < 50 mΩ (initial) | | **Insulation Resistance** | > 100 MΩ at 500V DC | | **Dielectric Strength** | 1,500V AC for 1 minute | | **Mechanical Life** | > 10,000 Cycles | | **Operating Temp** | -25°C to +85°C | --- ### 2. Key Components & Construction The "JR-1B-R" designation usually refers to specific physical attributes: * **Housing:** Made of high-temperature thermoplastic (usually UL 94V-0 rated for flame retardancy). * **Actuator:** The rocker part of the switch. The **"R"** in the suffix often denotes the color **Red** or a specific **Rectangular** shape depending on the manufacturer's datasheet. * **Terminals:** Silver-plated brass or copper alloy. These are usually designed for "Quick Connect" spade terminals or direct soldering. * **Mounting:** Snap-in mounting style for easy installation into a rectangular panel cutout. --- ### 3. Circuit Diagram (SPST) Most JR-1B-R units function as a simple ON-OFF bridge for the "Hot" (Live) wire in an AC circuit. ```text [Line In] ----( Terminal 1 ) | [Switch] <-- Actuator | [Load Out] ----( Terminal 2 ) ``` --- ### 4. Common Applications Due to its robust current rating (10A-15A), it is used in: 1. **PC Power Supplies (PSUs):** As the primary master power switch at the back of the unit. 2. **Power Strips:** For surge protection and manual cutoff. 3. **Lab Equipment:** Providing a physical disconnect for safety. 4. **Office Machines:** Printers, copiers, and shredders. --- ### 5. Identification Suffixes * **JR:** Series code (High current rocker). * **1B:** Circuit configuration (Internal contact arrangement). * **R:** Color indicator (Red) or Terminal type (Right-angle/Rear). *Check specific manufacturer datasheet to confirm.* ---
