The **M2REB-RBC-R** is an electronic component, specifically a **Miniature Toggle Switch** manufactured by **NKK Switches**. It belongs to the **M series**, which is widely recognized for its high reliability and diverse mounting options. Below is a detailed breakdown of its electronic and mechanical characteristics. --- ## 1. Technical Specifications The "M2REB-RBC-R" code defines specific parameters regarding the electrical rating, mounting style, and actuator type. | Feature | Specification | | :--- | :--- | | **Manufacturer** | NKK Switches | | **Series** | M Series (Miniature Toggles) | | **Circuit Type** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON - ON | | **Contact Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Termination Style** | Right Angle PC Pin (Horizontal Mount) | | **Actuator Type** | Flatted Lever (RBC Designator) | | **Mounting Type** | Through Hole, Right Angle | --- ## 2. Key Electronic Features ### A. Contact Material and Rating Unlike standard power switches, the "R" suffix in the M2 series usually indicates **Gold-plated contacts**. * **Logic Level Application:** The 0.4VA rating at 28V is designed specifically for low-energy circuits where reliability is critical. Gold prevents oxidation, ensuring a stable connection even after long periods of inactivity. * **Dry Circuit Compatibility:** It is ideal for signaling and data switching rather than high-power AC mains switching. ### B. Internal Construction * **Anti-Rotation Design:** The flatted lever is designed to resist rotation, ensuring the orientation of the actuator remains consistent. * **Epoxy Sealed Terminals:** The base is typically sealed with epoxy to prevent flux, solvents, and other contaminants from entering the contact area during soldering. * **High Torque Bushing:** The mechanical structure prevents the lever from transferring excessive force to the internal contacts during operation. ### C. Termination Configuration The **RBC-R** designation indicates a specific PC tail orientation: * **Right Angle (Horizontal):** The pins are bent at a 90-degree angle, allowing the switch to be mounted flat against a PCB while the actuator protrudes from the side of the enclosure. --- ## 3. Application Use Cases Due to its miniature size and logic-level reliability, this switch is commonly found in: 1. **Handheld Devices:** Where space is limited and low power consumption is required. 2. **Audio/Visual Equipment:** For signal routing or mode selection. 3. **Industrial Controls:** As a reset or configuration toggle on a control board. 4. **Medical Instrumentation:** Where high-reliability gold contacts are necessary for sensitive sensor data. ---
