The **WRS-141-R** is a specific model of a **Miniature Rocker Switch**. These components are widely used in consumer electronics, power strips, and industrial panels to provide a manual interface for connecting or breaking an electrical circuit. ### 1. Key Technical Specifications Below are the typical electronic and physical parameters for the WRS-141-R: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Switch Function** | ON - OFF | | **Contact Rating** | 16A @ 125VAC / 10A @ 250VAC | | **Mounting Type** | Panel Mount (Snap-in) | | **Termination Style** | Quick Connect / Solder Terminals | | **Mechanical Life** | ~100,000 Cycles | --- ### 2. Electronic Components & Anatomy The WRS-141-R consists of several critical internal and external parts: #### A. Actuator (The Rocker) * **Material:** Usually molded from Nylon or Polycarbonate. * **Function:** The physical interface the user presses. In the "R" variant (often denoting Red), it may be translucent if it includes an internal lamp. #### B. Housing * **Material:** Heat-resistant plastic (UL94V-2 rated). * **Feature:** Includes "plastic ears" or clips that allow the switch to snap securely into a rectangular cutout on a panel without screws. #### C. Internal Contacts (Stationary & Moving) * **Moving Arm (Bridges):** Usually made of a copper alloy with silver plating. * **Stationary Terminals:** These extend to the outside of the switch for wiring. * **Electronic Role:** When the rocker is toggled "ON," the bridge completes the circuit between the input and output terminals. #### D. Illumination (Optional depending on sub-model) * **Component:** If the model includes a light, it usually contains a **Neon Lamp** (for AC use) or an **LED** (for DC use) and a current-limiting resistor. * **Wiring:** This requires a third terminal (Neutral) to power the internal light. --- ### 3. Circuit Representation The WRS-141-R operates as a simple break in a wire. Here is how it is represented in a schematic: ```text [Power Source] ----(Terminal 1) \ (Terminal 2)---- [Load/Device] \ (Switch Open/OFF) ``` --- ### 4. Common Applications * **Power Strips:** Used as the master ON/OFF switch. * **Small Appliances:** Coffee makers, vacuum cleaners, and kitchen electronics. * **Industrial Controls:** Used in control boxes to engage specific modules.
