The **10TS-4D0-R** is a specific electronic component, typically categorized as a **Tactile Switch** or a **Micro Switch**. These components are widely used in consumer electronics, automotive controls, and industrial interfaces to provide a physical "click" feedback to the user. ### 1. Key Technical Specifications Based on the standard nomenclature for the 10TS series, here are the primary technical characteristics: | Parameter | Typical Value | | :--- | :--- | | **Switch Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuator Type** | Round Button / Stem | | **Operating Force** | ~160gf to 250gf (Depending on specific sub-variant) | | **Contact Rating** | 50mA @ 12V DC | | **Life Cycle** | 100,000 to 500,000 cycles | --- ### 2. Physical Construction and Pins The "4D0" and "R" in the part number often refer to the physical dimensions and packaging: * **Dimensions:** Usually a compact footprint (e.g., 4.5mm x 4.5mm or 6mm x 6mm). * **Height:** The "4D0" often correlates to a stem height of **4.0mm**. * **R (Tape & Reel):** Indicates that the parts are supplied on a reel for automated "Pick and Place" assembly machines. ### 3. Applications These switches are found in devices where space is limited but user input is required: 1. **Consumer Electronics:** Volume buttons on tablets, power buttons on cameras. 2. **Home Appliances:** Control panels for microwaves or washing machines. 3. **Medical Devices:** Handheld diagnostic tools. 4. **Computer Peripherals:** Reset buttons on routers or internal PCB triggers. ### 4. Typical Circuit Diagram The switch acts as a simple bridge. When pressed, it connects two internal terminals. ```text (Terminal 1) ----/ ---- (Terminal 2) (Switch Open) (Terminal 1) ---------- (Terminal 2) (Switch Closed/Pressed) ``` ---
