The **M2TT-13-R** belongs to the M2 series of miniature toggle switches manufactured by **NKK Switches**. These components are specifically designed for PC board mounting and are known for their high reliability and compact form factor. --- ## 1. Component Specifications The following table highlights the primary electrical and physical characteristics of the M2TT-13-R: | Feature | Specification | | :--- | :--- | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-OFF-ON | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC / 4A @ 30V DC | | **Contact Material** | Silver (standard) | | **Mounting Type** | Through-hole, Vertical PC Mount | | **Actuator Style** | Standard Bat Lever | | **Terminal Type** | PC Pin (Straight) | --- ## 2. Pin Configuration and Switching Logic As a **DPDT ON-OFF-ON** switch, it has six terminals. The logic operates as follows: * **Position 1 (Left/Up):** Connects Pin 2 to 1 and Pin 5 to 4. * **Position 2 (Center):** All circuits are Open (OFF). * **Position 3 (Right/Down):** Connects Pin 2 to 3 and Pin 5 to 6. --- ## 3. Key Electronic Features ### A. Anti-Jamming Design The actuator design features an internal "anti-jamming" mechanism. This prevents downward force on the toggle from damaging the internal contact mechanism, making it durable for industrial or high-use environments. ### B. High Dielectric Strength The switch is rated for a dielectric strength of **1,000V AC** minimum between contacts, which ensures safety against voltage spikes and prevents electrical arcing within the miniature housing. ### C. Epoxy Sealed Terminals The terminals are sealed with epoxy to prevent the entry of flux, solvents, or other contaminants during the soldering process. This is critical for maintaining low contact resistance over the life of the component. --- ## 4. Common Applications The M2TT-13-R is typically found in: 1. **Industrial Controls:** Manual override switches or mode selectors. 2. **Audio/Visual Equipment:** Signal routing and power toggles. 3. **Medical Devices:** Compact interface controls requiring high reliability. 4. **Test & Measurement:** Switching between different sensor inputs or measurement ranges.
