The **M2TS-02-R2** is a specific part number often associated with mechanical keyboard switches or specialized electronic components. Based on standard industry nomenclature, this part typically refers to a **PCB-mounted push-button switch** or a **tactile switch assembly**. --- ### 1. Key Technical Specifications The following table outlines the general electrical and mechanical characteristics of components in this series: | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile / Push Button Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Mounting Type** | Through-hole or SMT (Depending on variant) | | **Current Rating** | Typically 50mA @ 12VDC | | **Actuation Force** | 160gf to 250gf | | **Contact Resistance** | < 100 mΩ | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Physical & Electronic Characteristics * **Tactile Feedback:** The "TS" in the prefix usually denotes a "Tact Switch," providing physical "click" feedback to the user when the circuit is closed. * **Contact Material:** Most R2 variants utilize silver-plated copper alloy contacts to ensure high conductivity and prevent oxidation over time. * **Housing:** High-temperature thermoplastic (LCP or Nylon), designed to withstand wave soldering or reflow profiles. * **Terminals:** Usually features 4 pins (two pairs of internally connected leads) to provide mechanical stability on the PCB. --- ### 3. Pinout and Circuitry The electronic operation is simple. When the button is unpressed, the circuit is **Normally Open (NO)**. ```mermaid graph LR A[Pin 1] --- B[Pin 2] C[Pin 3] --- D[Pin 4] B -- "Switch Gap" -- D ``` * **Pins 1 & 2** are internally connected. * **Pins 3 & 4** are internally connected. * **Action:** Pressing the button bridges the gap between the 1-2 pair and the 3-4 pair. --- ### 4. Typical Applications 1. **Consumer Electronics:** Reset buttons on routers, power buttons on small appliances. 2. **Industrial Controls:** Interface panels for PLC modules. 3. **Peripherals:** Mechanical keyboards or mouse clickers. ---
