The **10TS-340-R** is a specific electronic component, typically categorized as a **surface-mount (SMD) tactile switch**. These components are widely used in consumer electronics, automotive controls, and industrial interfaces to provide a momentary "click" or tactile feedback when pressed. --- ## 1. Technical Specifications The following table summarizes the typical electrical and physical characteristics of the 10TS-340-R series: | Feature | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Style** | Surface Mount Device (SMD/SMT) | | **Actuator Height** | 3.40mm (approximate) | | **Contact Material** | Stainless Steel with Silver Plating | | **Operating Force** | 160gf to 260gf (varies by sub-model) | | **Electrical Rating** | 50mA / 12V DC | | **Contact Resistance** | < 100mΩ | | **Lifespan** | 50,000 to 100,000 cycles | --- ## 2. Key Components & Construction The 10TS-340-R is comprised of four primary internal parts that work together to create the switching action: 1. **Actuator (Button):** The top part that the user presses. In the 340-R model, this is usually a small plastic stem designed for vertical pressure. 2. **Contact Dome:** A precision-engineered metal dome. When pressed, it collapses to complete the circuit and provides the "tactile" feel. 3. **Base (Housing):** Heat-resistant plastic (often LCP or Nylon) that holds the internal components and withstands reflow soldering temperatures. 4. **Terminals:** The metal leads protruding from the base that are soldered onto the Printed Circuit Board (PCB). --- ## 3. Identification Breakdown The part number usually follows a specific manufacturer naming convention: * **10TS:** Series identifier (Tactile Switch). * **340:** Refers to the physical height of the actuator (3.40 mm). * **R:** Usually indicates **Tape and Reel** packaging, signifying that the parts are delivered on a spool for automated pick-and-place assembly machines. --- ## 4. Common Applications * **Consumer Electronics:** Power buttons on smartphones, volume rockers, and remote controls. * **Home Appliances:** Microwave control panels and washing machine interfaces. * **Computing:** Mouse buttons and laptop power switches. * **Automotive:** Interior lighting controls and dashboard buttons.
