The **M2TT-N6-R2** is a specific part number belonging to the **M2 series** of miniature toggle switches, manufactured by **Nidec Components (formerly Copal Electronics)**. These switches are designed for PC board mounting and are known for their high reliability and compact footprint. --- ### 1. Key Technical Specifications The "M2TT-N6-R2" code defines the physical and electrical characteristics of the switch. | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switching Function** | ON-ON (Two maintained positions) | | **Contact Rating** | Max: 6A @ 125VAC / 3A @ 250VAC / 4A @ 30VDC | | **Mounting Type** | Through-hole (PC Terminal) | | **Actuator Style** | Standard Toggle | | **Terminal Protection** | Epoxy sealed to prevent flux entry | --- ### 2. Breakdown of Part Numbering Manufacturers use specific strings to denote the build of the component. Here is how the M2TT-N6-R2 is likely structured based on Nidec/Copal standards: * **M2**: Series designation (Miniature Toggle Switches). * **TT**: Often indicates the terminal style or double-pole configuration. * **N6**: Specific to the rating or the actuator length/style. * **R2**: Packaging or RoHS compliance/Revision marker. --- ### 3. Electrical & Material Properties These switches are engineered for industrial and professional electronic equipment. * **Contact Resistance:** Typically less than 10mΩ to 20mΩ initially. * **Dielectric Strength:** Usually rated at 1,000V AC for one minute. * **Insulation Resistance:** Minimum 1,000MΩ at 500V DC. * **Mechanical Life:** Generally rated for 50,000 to 100,000 cycles. * **Operating Temperature:** Typically ranges from -25°C to +85°C. --- ### 4. Common Applications Due to its DPDT configuration (allowing it to control two separate circuits simultaneously), this part is commonly used in: * **Industrial Controls:** Mode selection or power switching. * **Communication Equipment:** Signal routing. * **Medical Instrumentation:** User interface controls. * **Testing & Measurement:** Powering on/off or switching between test modes. --- ### 5. Mechanical Dimensions While exact dimensions should be verified via the datasheet, the M2 series typically follows these standards: ```text Terminal Pitch: 4.7mm or 5.08mm Actuator Length: ~10mm to 12mm Body Width: ~12.5mm (for DPDT models) ```
