The **LRA911CWCW** refers to a specific rocker switch model commonly produced by manufacturers like **Marquardt** or **Carling**. It is an electromechanical component used to control the flow of electricity in various appliances and industrial equipment. ### 1. Component Specifications The electronic and physical characteristics of the LRA series rocker switch are typically defined by the following parameters: | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Current Rating** | 10A to 16A at 125V/250V AC | | **Termination** | Quick Connect / Solder Terminals | | **Actuator Style** | Curved Rocker | | **Mounting Type** | Panel Mount (Snap-in) | --- ### 2. Key Electronic Features #### A. Contact Mechanism The internal part consists of silver-plated copper alloy contacts. When the rocker is pressed, it moves a bridge piece that completes or breaks the electrical circuit. The "911" designation often implies a specific internal logic (On-Off). #### B. Housing and Material * **Insulation:** The body is made of high-quality thermoplastic (Polyamide/Nylon 6.6) designed to resist heat and provide electrical insulation. * **Dielectric Strength:** Usually rated for 1500V AC for 1 minute, ensuring that the voltage does not jump between the terminals and the panel. #### C. Environmental Ratings These switches are often rated for specific temperatures (e.g., T100 or T125), meaning they can operate reliably in environments reaching up to 125°C. --- ### 3. Wiring Diagram (SPST) Internally, the switch acts as a simple bridge. Below is the logic represented in a basic block: ```text [ Terminal 1 ] <-----( Moving Contact )-----> [ Terminal 2 ] | | Input Output (Line/Hot) (Load) ``` ### 4. Application Areas Because of its robust current handling, the LRA911 series is found in: * **Power Strips:** Used as the main power toggle. * **Kitchen Appliances:** Coffee makers, toasters, and blenders. * **Medical Equipment:** On/off switches for diagnostic tools. * **Industrial Panels:** Control interfaces for machinery. ---
