The **M2TT-7F-R2/BL** refers to a high-performance, miniature industrial toggle switch typically manufactured by companies like **Nidec Copal Electronics** (formerly Fujisoku). This specific series is designed for PC board mounting and is known for its high reliability in logic-level and power applications. --- ### 1. Key Technical Specifications Below is a breakdown of the typical electronic and mechanical characteristics for this part series: | Feature | Specification | | :--- | :--- | | **Contact Form** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC / 4A @ 30VDC | | **Terminal Type** | Right Angle PC Terminal (Horizontal Mount) | | **Actuator Style** | Standard Bat Toggle | | **Operating Temp** | -20°C to +85°C | | **Insulation Resistance** | 1000MΩ Min. | | **Dielectric Strength** | 1500VAC for 1 minute | --- ### 2. Electronic Component Breakdown The part number suffix and prefix represent specific engineering choices for the circuitry: * **M2T Series:** Indicates the "M2" miniature series, characterized by a process-sealed structure that protects the internals during soldering and cleaning. * **7F Logic:** Typically denotes the specific mounting orientation and terminal spacing. The **"7"** often refers to a Right-Angle (RA) mounting style, allowing the toggle to be accessed from the side of a PCB. * **R2 (Contact Material):** Usually signifies silver-plated contacts. Silver provides excellent conductivity for power applications but may require a minimum load to "wipe" oxidation. * **BL (Color/Finish):** Often refers to the aesthetic finish or a specific locking lever/bezel color, in this case, **Black**. --- ### 3. Applications and Use Cases The M2TT-7F-R2/BL is commonly found in environments requiring robust physical UI elements: 1. **Industrial Control Panels:** Used for mode selection where space on the PCB is limited. 2. **Telecommunications:** Signal switching in networking hardware. 3. **Medical Equipment:** High-reliability switching for diagnostic tools. 4. **Audio/Visual:** Routing signals in professional rack-mounted gear. --- ### 4. Mounting Geometry Because this is a **Right-Angle (R2/7F)** part, the pins are bent at 90 degrees. This allows the switch to sit flat on the PCB while the toggle protrudes through the side of the device enclosure. ```text Toggle Handle || ________||________ | Switch | | Body | |__________________| | | | <-- Right Angle Pins |__|__| (Plug into PCB) ```
