The **M2RT-6A-R/BL** is a specific model within the series of industrial-grade **Rotary Switches** or **Selector Switches**, typically manufactured by brands like *NIDEC COMPONENTS (formerly COPAL ELECTRONICS)* or similar industrial component providers. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Part Type** | Rotary Switch (Sub-miniature) | | **Circuit Configuration** | Double Pole, Double Throw (DPDT) / 2-Pole | | **Number of Positions** | 2 Positions | | **Switching Function** | ON - ON | | **Current Rating** | Typically 6A @ 125VAC / 3A @ 250VAC | | **Actuator Style** | Round Lever / Bat Toggle style (depending on series) | | **Termination Style** | PC Pin (Through-hole) or Solder Lug | | **Color Code** | BL = Blue / R = Red (typically refers to the body or lever cap) | --- ### 2. Key Electronic Characteristics #### A. Contact Mechanism The "RT" in the series often signifies a **Rotary-style Toggle** or a reinforced contact mechanism designed for high reliability. The internal contacts are usually silver-plated or gold-flashed to ensure low contact resistance and prevent oxidation over long periods of use. #### B. Power Handling Unlike signal-level DIP switches, the **6A** designation indicates this part is capable of handling significant power loads. It is suitable for: * AC Mains switching (125V/250V). * Motor control triggers. * Power supply mode selection. #### C. Mounting and Durability * **Sealing:** These parts are often washable or sealed to withstand soldering fluxes and industrial cleaning agents. * **Mechanical Life:** Designed for 25,000 to 50,000 cycles minimum. * **Dielectric Strength:** Usually rated for 1,000V AC for one minute, ensuring safety between the circuit and the operator. --- ### 3. Application Use Cases 1. **Industrial Machinery:** Used as a mode selector (e.g., Manual vs. Auto). 2. **Test Equipment:** Switching between different measurement ranges or input sources. 3. **Medical Devices:** Reliable power or state switching where accidental toggling must be minimized. 4. **Audio Equipment:** High-end routing where physical tactile feedback and low resistance are required. ---
