The **17TK-56-R** is a specific electronic component typically identified as a **standard tactile switch** or a **push-button switch**, often used in consumer electronics, automotive controls, and industrial interfaces. --- ### 1. Key Technical Specifications The "17TK" series generally refers to a specific form factor and actuation style. Below are the common technical parameters for this part: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Tactile Switch (Momentary Push Button) | | **Mounting Type** | Through-Hole (THT) or Surface Mount (SMD) | | **Circuit Type** | SPST (Single Pole Single Throw) - Normally Open | | **Current Rating** | ~50mA | | **Voltage Rating** | 12V DC | | **Actuation Force** | 160gf to 250gf (Commonly) | | **Operating Life** | 100,000 to 500,000 cycles | --- ### 2. Physical Characteristics * **Dimensions:** Usually a square base (e.g., 6mm x 6mm or 12mm x 12mm depending on the specific manufacturer sub-series). * **Stem Height:** The "56" in the part number often correlates to a specific stem height (e.g., 5.6mm) or a specific material/color variant. * **Feedback:** Provides "tactile" feedback, meaning the user feels a distinct "click" when the circuit is closed. --- ### 3. Common Applications Due to its reliability and small footprint, the 17TK-56-R is used in: 1. **Consumer Electronics:** Volume buttons on speakers, power buttons on monitors. 2. **Home Appliances:** Control panels for microwave ovens or washing machines. 3. **Computing:** Reset buttons on motherboards or peripheral input devices. 4. **Industrial:** Human-Machine Interface (HMI) panels. --- ### 4.
