The **WRS-4B1-R** is a specific type of **Rocker Switch** commonly used in consumer electronics, power strips, and small appliances. It is designed to act as a manual interface to connect or disconnect an electrical circuit. --- ### 1. Technical Specifications Below are the typical technical parameters for this component: | Feature | Specification | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Current Rating** | 10A @ 125VAC / 6A @ 250VAC | | **Contact Resistance** | ≤ 50mΩ | | **Insulation Resistance** | ≥ 100MΩ (500VDC) | | **Dielectric Strength** | 1500VAC / 1 minute | | **Mechanical Life** | > 10,000 Cycles | | **Mounting Type** | Panel Mount (Snap-in) | --- ### 2. Key Components & Materials The "Electronic Parts" within this assembly include: * **Actuator (The Rocker):** Usually made of Nylon (PA66). This is the part the user presses. * **Housing:** The plastic body that snaps into the device panel. * **Terminals:** Usually silver-plated brass or copper alloy. These are the metal pins at the bottom where wires are soldered or connected via quick-connect lugs. * **Contact Mechanism:** Inside the switch, a moving copper plate (the "bridge") makes or breaks the connection between the terminals. * **Internal Spring:** Provides the tactile "click" feel and ensures the contacts stay firmly in place when switched. --- ### 3. Pinout and Installation The WRS-4B1-R is a **2-pin** switch. Because it is an SPST switch, it acts as a simple gate: ```text [ Terminal 1 ] <---- Incoming Hot Wire (Line) | [Switch] | [ Terminal 2 ] <---- Outgoing to Load (Device) ``` **Note:** Since this model is a basic rocker (indicated by the 'R' suffix usually denoting Red or Round depending on the sub-manufacturer), ensure you check if your specific version has an integrated **Neon Lamp**. If it has 3 pins, one pin is dedicated to a Neutral connection to power the internal light. --- ### 4. Safety Considerations * **Voltage Limits:** Never exceed the rated voltage (250V). Doing so can cause internal "arcing," which leads to fire hazards. * **Heat Dissipation:** Ensure the terminals are tightly crimped or soldered. Loose connections create resistance, which generates heat and can melt the plastic housing.
