The **M2TS-11-R2** is a specialized electronic component, typically identified as a **high-precision, ultra-miniature toggle switch** or a specific **thermal/magnetic circuit protector**, depending on the manufacturer (most commonly associated with NKK Switches or circuit protection series). Below is a breakdown of the electronic parts and specifications related to this component. --- ### 1. Technical Specifications The "R2" suffix often denotes a specific terminal type (like right-angle PC terminals) or a specific material coating for environmental resistance. | Feature | Specification (Typical) | | :--- | :--- | | **Contact Rating** | 6A @ 125V AC / 3A @ 250V AC | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON - NONE - ON | | **Mounting Type** | Through Hole / Right Angle | | **Actuator Style** | Standard Lever / Toggle | | **Terminal Material** | Silver or Gold Plated Copper | --- ### 2. Key Internal Components The electronic functionality relies on several critical internal parts: * **Contact Mechanism:** Usually a "butt contact" or "sliding contact" mechanism. The silver alloy plating ensures low contact resistance and high reliability over thousands of cycles. * **Insulation Base:** Made from Diallyl Phthalate (DAP) or high-temp PPS plastic. This prevents electrical leakage between terminals and allows the part to withstand wave soldering temperatures. * **Torsion Spring:** Provides the "snap action" feel. It ensures that the transition between "ON" positions is fast, reducing internal arcing. * **Terminal Pins:** The R2 variant typically features **Epoxy Sealing** at the base of the pins to prevent solder flux or contaminants from entering the internal switch chamber. --- ### 3. Application Use Cases Because of its small footprint and high durability, it is used in: 1. **Telecommunications:** Signal switching in networking hardware. 2. **Medical Equipment:** Handheld diagnostic devices where space is premium. 3. **Test & Measurement:** Mode selection in oscilloscopes or multimeters. 4. **Audio/Visual:** Input routing for professional mixing consoles. --- ### 4. Dimensional Layout Most versions of this series follow a standard pitch for PCB integration: ```text [ Lever ] | | ------- <-- Bushing | | | Body | |_______| | | | <-- Right Angle Terminals (R2 Configuration) ```
