The **17TS-05-R** is a specific electronic component, typically categorized as a **Tactile Switch** (also known as a momentary push-button switch). These components are widely used in consumer electronics, industrial controls, and PCB designs where a tactile "click" feedback is required. --- ### 1. Technical Specifications Below are the general technical parameters for the 17TS series tactile switches: | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | Momentary Push Button (SPST) | | **Mounting Type** | Through-hole (DIP) or Surface Mount (SMD) | | **Dimensions** | 6mm x 6mm (Standard) | | **Height** | 5.0mm (indicated by the "05") | | **Actuation Force** | 160gf to 250gf | | **Contact Resistance** | < 100mΩ | | **Insulation Resistance** | > 100MΩ at 500V DC | | **Operating Life** | 100,000 cycles minimum | --- ### 2. Part Number Breakdown The nomenclature for this part usually follows this structure: * **17TS**: The series identifier (Tactile Switch). * **05**: Represents the **height** of the switch plunger (5.0mm measured from the base). * **R**: Often indicates **RoHS Compliance** or specific packaging (like Tape & Reel), though in some manufacturer catalogs, it can refer to the actuation force (Red stem/High force). --- ### 3. Key Internal Components A tactile switch like the 17TS-05-R consists of several precision-engineered parts: 1. **Cover (Metal/Plastic):** Protects the internal mechanism and provides a pivot point for the button. 2. **Plunger (Actuator):** The part you press. Its height (5mm) is critical for fitting through device enclosures. 3. **Contact Dome:** A metal "snap" dome. When pressed, it collapses to bridge the contacts and provides the tactile "click." 4. **Base:** The plastic housing that holds the terminals in place. 5. **Terminals:** Usually silver-plated brass or copper, used to solder the component to a PCB. --- ### 4. Common Applications * **Consumer Electronics:** Remote controls, microwave panels, and calculators. * **Computing:** Reset buttons on motherboards or peripheral input devices. * **Industrial:** Interface panels for machinery and testing equipment. * **Prototyping:** Frequently used on breadboards for Arduino or Raspberry Pi projects. ---
