The part number **M2TT-NC-R2/CE** refers to a high-quality industrial toggle switch manufactured by **Nidec Components (formerly Copal Electronics)**. This specific model is part of the M2 series, known for its reliability in sub-miniature applications. --- ### 1. Technical Specifications Breakdown The following table outlines the primary electrical and physical characteristics of the M2TT-NC-R2/CE: | Feature | Specification | | :--- | :--- | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switching Function** | ON - ON | | **Contact Rating** | 6A @ 125VAC / 3A @ 250VAC / 4A @ 30VDC | | **Terminal Type** | PC Pin (Right Angle) | | **Actuator Style** | Standard Toggle | | **Dielectric Strength** | 1,000V AC for 1 minute | | **Insulation Resistance** | 1,000 MΩ minimum | | **Operating Temperature** | -25°C to +85°C | --- ### 2. Key Component Features * **Sub-miniature Design:** Designed for high-density mounting on Printed Circuit Boards (PCBs) where space is limited. * **R2 Configuration:** The "R2" suffix indicates a **Right Angle** terminal orientation. This is ideal for edge-mounting on a PCB so the toggle protrudes horizontally from the enclosure. * **Dual Pole (DPDT):** It can control two separate circuits simultaneously, providing versatility for signal routing or power management. * **Safety Approvals (/CE):** The suffix denotes compliance with European safety standards (CE marking), ensuring it meets health, safety, and environmental protection requirements. --- ### 3. Internal Construction The electronic parts within this switch are engineered for longevity: 1. **Contacts:** Usually made of silver or gold-plated alloys to ensure low contact resistance and prevent oxidation. 2. **Housing:** Constructed from high-heat resistant resin (typically UL94V-0 rated) to withstand wave soldering processes. 3. **Mechanism:** Features a "molding-in" terminal construction which prevents flux or solder entry during the manufacturing process, protecting the internal contact points. --- ### 4. Typical Applications * **Telecommunications:** Used in networking hardware for mode selection. * **Industrial Control:** Panel-mounted switches for machine settings. * **Medical Equipment:** High-reliability switching for diagnostic tools. * **Test & Measurement:** Calibration or range selection toggles.
