The **M2TS-0B-R2/C** is a specialized electronic component, typically categorized as a **Surface Mount (SMT) Micro-Switch** or a miniature tactile switch used in compact electronic assemblies. --- ### 1. Key Technical Specifications While specific data can vary by manufacturer (often associated with brands like Panasonic or Omron in similar series), the general specifications for this part class are as follows: | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch / Micro-Switch | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Actuation Type** | Top Actuated | | **Circuit** | SPST (Single Pole Single Throw) | | **Switch Function** | Off-Mom (Momentary) | | **Contact Rating** | Usually 10mA to 50mA @ 12VDC | | **Operating Force** | 1.0N to 2.5N (Model dependent) | --- ### 2. Physical Characteristics The "0B-R2/C" suffix often denotes specific packaging and physical orientation details: * **Form Factor:** Designed for high-density PCB layouts where vertical space is limited. * **Termination:** Gull-wing or J-lead terminals for automated pick-and-place soldering. * **R2/C Designation:** Often refers to the **Tape and Reel** packaging specification (R2) and the **RoHS Compliance** (C) or specific internal Revision codes. --- ### 3. Internal Construction A switch of this type consists of four primary internal electronic parts: 1. **Actuator (Stem):** The physical button that the user presses. 2. **Contact Dome:** A snap-action metal disc that provides tactile feedback and completes the electrical circuit when compressed. 3. **Base:** A high-temperature thermoplastic (LCP) that holds the terminals. 4. **Terminals:** Silver or gold-plated copper alloy for low contact resistance and high solderability. --- ### 4. Common Applications Due to its small footprint, the M2TS series is found in: * **Consumer Electronics:** Smartphones, tablets, and wearable devices. * **Automotive:** Key fobs and steering wheel controls. * **Industrial:** Reset buttons on miniature sensor modules. * **Medical:** Portable diagnostic equipment. --- ### 5. Soldering Profile As an SMT component, it is designed to withstand standard **Lead-Free Reflow** temperatures. ```cpp // Typical Reflow Parameters Preheat_Temp: 150°C - 200°C Peak_Temp: 260°C (max) Time_at_Peak: 5 - 10 seconds ```
