The **WRS-1B2-R** is a standard electronic switch component, typically classified as a **Rocker Switch**. It is widely used in power distribution panels, household appliances, and industrial control systems to manually open or close an electrical circuit. --- ### ## Technical Specifications Below is a breakdown of the core electronic and mechanical parameters for the WRS-1B2-R: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuitry** | SPST (Single Pole, Single Throw) | | **Function** | ON - OFF | | **Current Rating** | 15A @ 125VAC / 10A @ 250VAC | | **Terminal Type** | Quick Connect (Solder lug or 4.8mm/6.3mm tabs) | | **Contact Resistance** | ≤ 50mΩ | | **Insulation Resistance** | ≥ 100MΩ (500VDC) | | **Dielectric Strength** | 1500VAC / 1 minute | | **Mechanical Life** | > 10,000 Cycles | --- ### ### Key Electronic Components & Materials The reliability of the WRS-1B2-R depends on several internal parts: 1. **Contact Points:** Usually made of a **Silver Alloy** (AgNi or AgSnO2) to ensure high conductivity and resistance to electrical arcing during switching. 2. **Actuator (Rocker):** Made of **Nylon 66 (UL94V-2)**, which provides insulation for the user and heat resistance. 3. **Spring Mechanism:** A high-tension internal spring ensures a "snap-action" movement, reducing the time the contacts stay in a semi-connected state, which prevents overheating. 4. **Housing:** The outer body is made of fire-retardant plastic designed to fit into a rectangular panel cutout. --- ### ### Wiring Configuration Since this is an **SPST** switch, it features two terminals. In a typical electronic circuit, it is placed on the "Hot" or "Positive" line: * **Terminal 1:** Input from the Power Source. * **Terminal 2:** Output to the Load (Device). *Note: The "R" in the part number often signifies a specific color (Red) or a specific ROHS compliance standard, depending on the manufacturer (e.g., Well Buying or local generic brands).* ---
