The **SWT6-R7YTR** 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 physical user interface is required. --- ### 1. General Specifications Based on the part numbering convention (common for manufacturers like Diptronics or similar switch specialists), here are the typical technical characteristics: | Feature | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Actuator Style** | Round Button / Stem | | **Contact Arrangement** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Operating Force** | Usually 160gf or 250gf (varies by sub-type) | | **Dimensions** | 6mm x 6mm (Base) | --- ### 2. Key Physical Features * **Surface Mount Design (SMT):** The "R" in many switch codes indicates "Reel" packaging, and the "T" often refers to "Top Actuated." This part is designed to be soldered directly onto the surface of a PCB rather than through holes. * **Tactile Feedback:** It provides a distinct "click" sensation to the user, confirming that the circuit has been closed. * **Durability:** Most switches in this series are rated for 100,000 to 500,000 cycles. --- ### 3. Electrical Characteristics These parts are designed for low-power signal switching, not for driving heavy loads: ```cpp // Typical Electrical Limits Max_Voltage: 12V DC; Max_Current: 50mA; Insulation_Resistance: >100M ohms; Contact_Resistance: <100m ohms; Dielectric_Strength: 250V AC for 1 minute; ``` --- ### 4. Common Applications * **Consumer Electronics:** Volume buttons, power buttons on remote controls, and household appliances. * **Computing:** Reset buttons on motherboards or peripheral input devices. * **Instrumentation:** Mode selection buttons on handheld testing equipment. --- ### 5. Footprint and Layout The 6x6mm footprint is an industry standard. When designing a PCB for the **SWT6-R7YTR**, ensure the "Gull-wing" or "J-lead" pads match the datasheet to allow for proper solder filleting during the reflow soldering process.
