## WRS-511-R Electronic Specifications and Features The **WRS-511-R** is a specific model of a **Miniature Rocker Switch**, typically manufactured by brands like **Well Buying** or found in industrial electronic catalogs. It is widely used in power supply units, consumer electronics, and small appliances. --- ### 1. Technical Specifications The electrical integrity of the WRS-511-R is defined by its current-carrying capacity and insulation properties. | Parameter | Specification | | :--- | :--- | | **Switch Type** | SPST (Single Pole Single Throw) | | **Circuit Function** | ON - OFF | | **Current Rating** | 10A 125VAC / 6A 250VAC | | **Contact Resistance** | 50mΩ Max (Initial) | | **Insulation Resistance** | 100MΩ Min at 500VDC | | **Dielectric Strength** | 1,500VAC for 1 minute | | **Electrical Life** | 10,000 Cycles | --- ### 2. Physical and Material Composition The "parts" of the switch are constructed to ensure safety and durability under high thermal conditions. * **Actuator (Rocker):** Usually made of Nylon 66 (UL 94V-2). The "-R" in the model name often signifies a **Red** color or a specific **Rectangular** shape. * **Housing/Body:** Constructed from fire-resistant Nylon. Designed for "Snap-in" mounting into a panel cutout. * **Terminals:** Silver-plated copper alloy. These are typically **Quick Connect (Solder)** tabs (4.8mm or 0.187"). * **Contacts:** Silver alloy to minimize arcing and reduce electrical resistance during operation. --- ### 3. Pin Configuration (SPST) Since the WRS-511-R is a Single Pole Single Throw switch, it generally features **two terminals**: 1. **Terminal 1 (Input/Line):** Connects to the incoming power source. 2. **Terminal 2 (Output/Load):** Connects to the device or component being powered. When the rocker is pressed to the "ON" position, the internal contact bridge closes the gap between these two terminals, completing the circuit. --- ### 4. Applications Due to its 6A/10A rating, this part is commonly found in: * Computer power supply units (PSUs). * Office equipment (printers, scanners). * Small kitchen appliances. * Power strips and surge protectors. ---
