The **R2-1P3N-R** is a specific model of a **Miniature Toggle Switch**. It is a common electromechanical component used to control the flow of electricity in a circuit through a physical lever mechanism. ### 1. Key Technical Specifications Below is a breakdown of the typical electronic and physical characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Switch Function** | SPDT (Single Pole Double Throw) | | **Operation** | ON - ON (Latched) | | **Current Rating** | ~6A at 125VAC / 3A at 250VAC | | **Terminal Type** | Solder Lug | | **Mounting Type** | Panel Mount | | **Actuator Style** | Standard Round Bat Lever | | **Bushing Size** | M6 x 0.75 | --- ### 2. Detailed Part Breakdown #### A. Circuitry: SPDT (Single Pole Double Throw) This part features three terminals. The middle terminal is the "Common" pin. Depending on the position of the toggle, the common pin connects to either the top pin or the bottom pin. This allows the switch to: * Switch between two different output devices. * Act as a simple ON/OFF switch (by leaving one outer pin disconnected). #### B. Mechanical Build * **Housing:** Usually constructed from phenolic resin or high-temperature plastic to provide electrical insulation. * **Contacts:** Typically silver-plated copper alloy to ensure low contact resistance and prevent oxidation. * **Mounting:** It comes with a threaded bushing, a locking washer, and a hex nut to secure it through a hole in a control panel. #### C. Typical Applications * **Audio Equipment:** Selecting between different signal paths or inputs. * **Industrial Controls:** Manual overrides for relays or sensors. * **DIY Electronics:** Power switching for battery-operated hobby projects. --- ### 3. Wiring Logic To use the R2-1P3N-R in a basic circuit, follow this logic: ```markdown Terminal 1 (L1) <--- Connected when lever is DOWN Terminal 2 (COM) <--- Input Power / Signal Terminal 3 (L2) <--- Connected when lever is UP ``` ---
