The **15TS-06-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, industrial controls, and PCB designs to provide a tactile "click" feedback to the user when a circuit is closed. --- ### 1. Technical Specifications The following table outlines the general technical parameters typical for the 15TS series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Through-Hole (DIP) or SMD (depends on sub-series) | | **Circuit** | SPST - NO (Single Pole Single Throw - Normally Open) | | **Current Rating** | ~50mA | | **Voltage Rating** | 12V DC | | **Contact Resistance** | < 100mΩ | | **Operating Force** | Typically 160gf to 250gf | | **Travel (Stroke)** | 0.25mm ± 0.1mm | --- ### 2. Key Features * **Tactile Feedback:** Provides a distinct physical "click" sensation and audible sound when pressed, confirming the actuation to the user. * **Compact Footprint:** Designed for high-density mounting on Printed Circuit Boards (PCBs). * **Durability:** High mechanical life cycle, often rated for 100,000 to 500,000 presses. * **RoHS Compliant:** The "R" suffix usually denotes compliance with RoHS (Restriction of Hazardous Substances) standards. --- ### 3. Pin Configuration & Working Principle The switch usually features 4 pins, but it acts as a **Single Pole Single Throw (SPST)** device. 1. **Internal Wiring:** Pins are typically connected in pairs (Pin 1 to 2, and Pin 3 to 4). 2. **Actuation:** When the button is pressed, the metal dome inside collapses, bridging the connection between the two pairs of pins. 3. **Momentary Action:** The circuit is only closed while the button is being held down. Once released, the internal spring (dome) pushes the button back to its original position, breaking the circuit. --- ### 4. Common Applications * **Consumer Electronics:** Remote controls, microwave panels, and calculators. * **Computer Peripherals:** Reset buttons on motherboards or buttons on monitors. * **Industrial:** Control panels, timers, and instrumentation. * **Prototyping:** Frequently used with Arduino or Raspberry Pi on breadboards for user input.
