The **10TS-3A6-R** is a specific model of a **Tactile Switch** (also known as a momentary push-button switch). These components are widely used in consumer electronics, automotive controls, and industrial panels to provide a physical "click" sensation and complete a circuit when pressed. Below is a detailed breakdown of its specifications and characteristics. ### 1. Technical Specifications The following table outlines the typical electrical and mechanical properties for this series: | Feature | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | ≤ 100 mΩ | | **Insulation Resistance** | ≥ 100 MΩ (100V DC) | | **Operating Force** | 160gf ± 50gf (Standard) | | **Travel** | 0.25mm ± 0.1mm | | **Life Cycle** | ~100,000 Cycles | | **Mounting Type** | SMD (Surface Mount Device) | --- ### 2. Physical Construction The "10TS" series usually follows a standard footprint. Breaking down the parts of the switch: * **Actuator (Stem):** The top part you press. In the "3A6" designation, the "6" often refers to the **height** of the switch (e.g., 6.0mm). * **Contact Dome:** A stainless steel or copper alloy disc that collapses when pressed to provide the tactile "snap" and bridge the electrical contacts. * **Housing:** High-temperature plastic (LCP or Nylon) designed to withstand Reflow Soldering temperatures. * **Terminals:** Silver-plated brass or copper for high conductivity and easy soldering. --- ### 3. Part Number Decoding While specific manufacturers vary slightly, the nomenclature usually breaks down as follows: 1. **10TS:** Series identifier (Miniature Tactile Switch). 2. **3A6:** Dimensions and Actuator height. * *3A* typically refers to a 3.x mm x 3.x mm base size. * *6* refers to a total height of 6.0mm from the PCB. 3. **-R:** Generally indicates **Tape & Reel** packaging, suitable for automated Pick-and-Place assembly machines. --- ### 4. Typical Applications * **Consumer Electronics:** Volume buttons on smartphones, remote controls, and calculators. * **Computing:** Reset buttons on motherboards or peripheral input devices. * **Industrial:** Interface panels for CNC machines or handheld testing equipment. * **Wearables:** Power buttons for smartwatches due to the small SMD footprint. --- ### 5. Schematic Symbol In a PCB design environment (like Altium or KiCad), the switch is represented simply: ```text Terminal 1 o-------/ -------o Terminal 2 (Momentary NO) ```
