The **M2TT-13-R** is a specific electronic component, primarily known as a **Slide Switch** or **Toggle Switch** (depending on the specific series iteration) manufactured by **Nidec Copal Electronics**. This component is part of the **M2 series**, which is designed for high reliability and compact integration on Printed Circuit Boards (PCBs). --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Slide / Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | On-On | | **Current Rating** | ~0.4VA Max (Logic Level) | | **Voltage Rating** | 28V AC/DC Max | | **Mounting Type** | Through-Hole (Right Angle) | | **Contact Resistance** | 20 mΩ Max | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Functional Description * **DPDT (Double Pole Double Throw):** This means the switch controls two separate circuits simultaneously. Each "pole" has one common terminal and two possible "throw" terminals. * **Logic Level Application:** The "R" in the suffix often denotes gold-plated contacts. Gold is used because it does not oxidize, ensuring a reliable electrical connection at very low currents (dry circuits) where silver contacts might fail due to surface film buildup. * **Right Angle Terminal:** The "13" in the part number typically refers to the terminal style. In this case, it indicates a right-angle PC terminal, allowing the switch to be operated from the edge of the board. --- ### 3. Construction and Materials The M2TT-13-R is built to withstand industrial environments: 1. **Housing:** Heat-resistant resin (often Polyphenylene Sulfide) to survive wave soldering. 2. **Contacts:** Gold-plated copper alloy for high-reliability signal switching. 3. **Actuator:** Durable plastic or metal lever designed for thousands of cycles. 4. **Sealing:** These units are often twin-contact, providing high contact reliability through a "wiping" action when flipped. --- ### 4. Typical Applications Due to its small footprint and DPDT configuration, it is commonly found in: * **Telecommunications:** Signal routing and mode selection. * **Medical Instrumentation:** Low-power device settings. * **Test & Measurement:** Calibration toggles and power-on/off for handheld meters. * **Embedded Systems:** DIP switch replacements for user configuration. ---
