The **HRS-31-R** refers to a specific model of a **Miniature Rocker Switch**. These components are widely used in consumer electronics, industrial panels, and power strips to connect or disconnect an electrical circuit. --- ### 1. General Specifications The HRS-31-R is characterized by its compact size and high reliability. Below are the typical technical parameters: | Feature | Specification | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Switch Function** | ON-OFF | | **Contact Rating** | 10A 125VAC / 6A 250VAC | | **Contact Resistance** | 50mΩ Max | | **Insulation Resistance** | 100MΩ Min (500VDC) | | **Dielectric Strength** | 1500VAC for 1 minute | | **Operating Temperature** | -25°C to +85°C | --- ### 2. Key Components and Design * **Actuator (The Rocker):** Usually made of Nylon 66. The "R" in the suffix often denotes the color **Red**, though it can sometimes refer to a Round shape depending on the specific manufacturer series. * **Housing:** A flame-retardant plastic body designed to be "snap-in" mounted into a rectangular or circular panel cutout. * **Terminals:** Usually made of silver-plated copper alloy. These are designed for quick-connect spade lugs or direct soldering. * **Internal Contacts:** Employs a moving bridge mechanism that "rocks" to bridge the gap between two stationary contacts. --- ### 3. Pinout and Installation Since this is an **SPST** (Single Pole Single Throw) switch, it typically features **2 pins**: 1. **Pin 1 (Line In):** Connects to the incoming power source. 2. **Pin 2 (Load Out):** Connects to the device or component being powered. > **Note:** Because it is a simple ON-OFF switch, it acts as a gatekeeper in the "Hot" or "Live" wire of a circuit. --- ### 4. Typical Applications * **Power Strips:** Used as the main reset or power toggle. * **Kitchen Appliances:** Coffee makers, blenders, and toasters. * **Computer Peripherals:** External hard drive enclosures and monitor power buttons. * **Industrial Control:** Small control panels for DIY electronics and machinery.
