The **SWT8-R2KTR** 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 interfaces, and industrial controls to provide a physical "click" feel and complete an electrical circuit when pressed. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMT/SMD) | | **Circuit Configuration** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuator Type** | Standard Round Button | | **Dimensions** | Typically 6mm x 6mm (Standard "SWT8" series footprint) | | **Termination Style** | Gull Wing (SMD Leads) | | **Packaging** | Tape & Reel (indicated by the "TR" suffix) | --- ### 2. Physical and Electrical Attributes #### Electrical Ratings * **Contact Current Rating:** Usually rated for **50mA**. * **Voltage Rating:** Typically **12V DC**. * **Contact Resistance:** Low initial resistance (often <100mΩ) to ensure signal integrity. * **Dielectric Strength:** Usually 250V AC for 1 minute. #### Mechanical Characteristics * **Operating Force:** Generally falls between **160gf to 260gf** (Gram-force), providing a distinct tactile response. * **Travel:** Short travel distance, usually **0.25mm**, ensuring rapid actuation. * **Durability:** Rated for a high number of cycles (often 100,000 to 500,000 presses). --- ### 3. Decoding the Part Number (SWT8-R2KTR) The part number follows a standard industry nomenclature for electronic components: * **SWT8:** Refers to the series (Tactile switch, 8 series usually denoting a specific size/form factor). * **R:** Often denotes the actuator height or a specific material (e.g., Rubber or Raised). * **2K:** Typically indicates the **Operating Force** (e.g., 260gf). * **TR:** Stands for **Tape & Reel**, meaning the parts are packaged on a continuous strip for use in automated Pick-and-Place assembly machines. --- ### 4. Common Applications Due to its small footprint and SMD design, this part is found in: 1. **Consumer Electronics:** Remote controls, microwave panels, and digital cameras. 2. **Computing:** Reset buttons on motherboards or peripheral input devices. 3. **Industrial:** Interface panels for machinery and handheld testing equipment.
