The **TS-0B-R** typically refers to a specific model of **Tactile Push Button Switch**. These components are widely used in consumer electronics, industrial controls, and PCB prototyping due to their small footprint and tactile feedback. --- ### 1. General Specifications The TS-0B-R is a momentary switch, meaning it only closes the circuit while the button is being physically pressed. | Feature | Typical Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Through-Hole (DIP) or SMD (model dependent) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Operating Force** | 160gf to 250gf (Grams-force) | | **Travel Distance** | 0.25mm ± 0.1mm | | **Voltage Rating** | 12V DC | | **Current Rating** | 50mA | --- ### 2. Physical Construction The "R" suffix often denotes a specific packaging or physical orientation (such as **Right Angle** or **Red** button cap, depending on the manufacturer’s datasheet). * **Actuator:** The top part pressed by the user. * **Cover:** Usually metal, securing the internal components. * **Contact Dome:** A precision-engineered metal disc that snaps down when pressed, providing the "click" sound and tactile feel. * **Terminals:** Usually silver-plated brass for high conductivity and easy soldering. --- ### 3. Pin Configuration and Circuit Most tactile switches in this series have 4 pins. While there are 4 physical legs, they are internally connected in pairs to provide mechanical stability on the PCB. ```text Terminal 1 ---[ Switch ]--- Terminal 3 Terminal 2 ---[ ]--- Terminal 4 (Note: 1 & 2 are usually connected, 3 & 4 are usually connected) ``` ### 4. Common Applications * **Computer Peripherals:** Reset buttons, power buttons. * **Consumer Electronics:** Microwave panels, TV control buttons. * **Embedded Systems:** Input buttons for Arduino/Raspberry Pi projects. * **Instrumentation:** Digital multimeters and interface panels. --- ### 5. Soldering Recommendations To ensure the longevity of the TS-0B-R, follow these thermal guidelines: * **Hand Soldering:** 350°C for maximum 3 seconds. * **Wave Soldering:** 260°C for maximum 5 seconds. * **Storage:** Avoid high humidity to prevent oxidation of the silver-plated terminals.
