The **M2RT-1F-R** is a high-performance, sub-miniature toggle switch manufactured by **NKK Switches**. It is part of the M series, specifically designed for PC board mounting where space is limited and reliability is critical. --- ### 1. Technical Specifications The following table summarizes the primary electronic and physical characteristics of the M2RT-1F-R: | Parameter | Specification | | :--- | :--- | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - NONE - ON | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC / 4A @ 30V DC | | **Terminal Type** | Right Angle PC Mount (Horizontal) | | **Actuator Style** | Flatted Lever | | **Contact Material** | Silver (Standard) | | **Operating Temp Range** | -30°C to +85°C | --- ### 2. Key Electronic Components & Design The "M2RT-1F-R" part number can be broken down to understand its internal construction: * **Dual Pole Double Throw (DPDT):** Internally, it controls two separate circuits simultaneously. It has six terminals: two common pins and four output pins (two for each common). * **Bushing Mount & Support Bracket:** The "R" suffix often denotes the right-angle orientation. It includes a reinforced bracket to ensure that mechanical stress from toggling doesn't snap the solder joints on the PCB. * **Anti-Rotation Design:** The internal mechanism is designed to prevent the lever from rotating, which protects the internal contact points from misalignment. * **High Torque Bushing:** The construction is ruggedized to prevent the bushing from separating from the body during installation or heavy use. --- ### 3. Common Applications Due to its small footprint and horizontal mounting, this part is frequently found in: 1. **Telecommunications:** Signal switching in networking hardware. 2. **Medical Equipment:** Control interfaces for portable diagnostic devices. 3. **Audio/Visual:** Input selectors for compact mixers or amplifiers. 4. **Industrial Controls:** Mode selection on handheld controllers. ---
