The **M2TS-31-R/K** is a specific model of a **Miniature Toggle Switch**, typically manufactured by companies like NKK Switches. These components are designed for panel mounting and are used to control the flow of electricity within a circuit through a physical lever action. --- ### Technical Specifications Below are the primary electronic and physical characteristics of this part: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-ON (Two stable positions) | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC | | **Terminal Type** | PC (Printed Circuit) Pins / Solder Lug | | **Actuator Style** | Standard Lever | | **Mounting Type** | Panel Mount (Threaded Bushing) | --- ### Key Electronic Components & Features #### 1. SPDT Configuration As a **Single Pole Double Throw** switch, it has one input (Common) and two possible outputs. * In position A, terminal 1 is connected to terminal 2. * In position B, terminal 2 is connected to terminal 3. * This makes it ideal for switching between two different functions or power paths. #### 2. Contact Mechanism The internal contacts are usually made of **silver alloy** or **gold plating**. * **Silver:** High conductivity, best for power applications. * **Gold:** Prevents oxidation, best for low-level logic signals (dry circuits). #### 3. Insulation & Dielectric Strength The body is constructed from high-insulation materials (like Diallyl Phthalate resin) to ensure that electricity does not arc between the terminals or leak to the metal frame. It typically features a dielectric strength of **1,000V AC minimum** between contacts. #### 4. The "R/K" Designation In the NKK part numbering system: * **R:** Often refers to the specific rating or a RoHS compliance indicator. * **K:** Usually denotes the type of actuator or the finish of the toggle lever (e.g., a matte or chrome finish). --- ### Common Applications * **Industrial Control Panels:** For manual overrides or mode selection. * **Audio Equipment:** To toggle between input sources or bypass effects. * **Medical Devices:** Used in power-on/off sequences due to high reliability. * **Test & Measurement:** For switching ranges or signal paths in lab gear.
