The **WRS-441-R** is a specific model of a **Miniature Rocker Switch**. These components are widely used in power distribution and user-interface panels for electronic devices. Below is a detailed breakdown of its electronic and mechanical parts. --- ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuitry** | SPST (Single Pole Single Throw) | | **Switch Function** | ON-OFF | | **Current Rating** | Typically 16A @ 125VAC / 10A @ 250VAC | | **Mounting Type** | Panel Mount (Snap-in) | | **Termination Style** | Quick Connect / Solder Terminals | --- ### 2. Key Electronic & Physical Components #### A. The Actuator (The "Rocker") The visible part of the switch that the user presses. * **Material:** Usually made of heat-resistant Nylon 66. * **Markings:** Often features "I" and "O" symbols to represent the closed (ON) and open (OFF) states. #### B. The Housing (Body) The rectangular frame that holds the internal components. * **Snap-in Clips:** It features flexible plastic tabs that allow it to be pushed into a pre-cut rectangular hole in a metal or plastic panel without needing screws. #### C. Internal Contacts * **Moving Contact (Armature):** A metal piece (often copper alloy) that tilts back and forth inside the switch. * **Stationary Contacts:** The fixed points where the circuit is completed. These are often silver-plated to ensure high conductivity and minimize "arcing" (sparks) when switching under load. #### D. The Terminals Located at the bottom of the switch, these connect the switch to the rest of the electronic circuit. * **WRS-441-R** typically features two terminals since it is a **Single Pole Single Throw** (SPST) device. * **Material:** Brass or Copper with tin or silver plating for easier soldering or terminal crimping. --- ### 3. Circuit Representation The WRS-441-R functions as a simple "Gate" in a circuit: ```text [ Terminal 1 ] ----------/ ---------- [ Terminal 2 ] (Source) (Switch) (Load) ``` ### 4. Application Common Uses * **Power Strips:** Used as the main master power toggle. * **Appliances:** Found in coffee makers, vacuum cleaners, and desktop PCs. * **Industrial Panels:** Used for low-to-medium voltage control signals. ---
