The **10TS-640-R** is an electronic component, specifically a **Surface Mount (SMT) Tactile Switch**. These components are widely used in consumer electronics, industrial controls, and medical devices as momentary push-button interfaces. --- ### 1. Key Technical Specifications Based on the industry standards for the 10TS series, here are the primary electrical and mechanical characteristics: | Property | Specification | | :--- | :--- | | **Mounting Type** | Surface Mount (SMT / SMD) | | **Circuit** | SPST - NO (Single Pole Single Throw - Normally Open) | | **Switch Function** | Momentary (Turns ON when pressed, OFF when released) | | **Actuator Height** | 4.3mm to 5.0mm (standard for the 640 series) | | **Operating Force** | Typically 160gf or 250gf | | **Contact Rating** | 50mA @ 12VDC | | **Base Dimensions** | 6.0mm x 6.0mm | --- ### 2. Physical Construction The "10TS" series follows a standard 6x6mm footprint. Its anatomy consists of four main parts: 1. **The Cover:** Usually made of stainless steel or brass to protect the internal dome. 2. **The Actuator (Stem):** The plastic "button" you press. The "640" in the part number often designates the height or specific stem style. 3. **The Contact Dome:** A metallic disk that provides tactile feedback (the "click") and completes the electrical circuit. 4. **The Base:** A high-temperature thermoplastic (LCP or Nylon) that houses the terminals and withstands reflow soldering. --- ### 3. Part Number Breakdown While manufacturers may vary slightly, the nomenclature usually follows this logic: * **10TS:** Series identifier (standard 6x6mm tactile switch). * **640:** Size/Height indicator (e.g., 6.0mm x 6.0mm base with specific stem height). * **R:** Packaging code, typically standing for **Tape & Reel**. This indicates the parts are packaged for automated pick-and-place assembly machines. --- ### 4. Applications These switches are found in almost any device requiring user input: * **Computer Peripherals:** Keyboards, mouse buttons, and reset switches. * **Home Appliances:** Control panels on microwaves or washing machines. * **Handheld Devices:** Power buttons on remote controls and portable gaming consoles. * **Automotive:** Dashboard controls and key fobs.
