The **M6SWVS-AD-R/K** is a specific variant of a professional-grade tactile switch, typically manufactured by **Alps Alpine** (or compatible industrial suppliers). These components are widely used in automotive interfaces, consumer electronics, and industrial controls. --- ## 1. Component Overview The part number indicates a **Surface Mount Device (SMD)** tactile switch designed for vertical actuation. It is engineered for high durability and a specific tactile feedback profile. ### Technical Specifications | Feature | Description | | :--- | :--- | | **Type** | Tactile Switch (Push Button) | | **Mounting Type** | Surface Mount (SMT/SMD) | | **Orientation** | Vertical / Top Actuated | | **Operating Force** | Typically 1.6N to 2.5N (varies by sub-series) | | **Life Cycle** | 100,000 to 500,000 cycles | | **Travel** | Short travel (approx. 0.25mm) | | **Termination** | Gull-wing or J-bend leads | --- ## 2. Key Features * **Sealed Construction:** The "W" in many of these sequences often denotes a wash-tight or sealed structure, protecting the internal contacts from dust and moisture (IP67 rated in some variants). * **Compact Footprint:** Designed for high-density PCB layouts. * **Snap-in Feel:** Provides a clear "click" or tactile bump to confirm user input. * **Reflow Solderable:** Material composition allows it to withstand high temperatures during industrial soldering processes. --- ## 3. Internal Schematic Internally, this is a **SPST (Single Pole Single Throw)** Normally Open switch. ```text (1) ---- [ ] ---- (2) | [Actuator/Dome] | (3) ---- [ ] ---- (4) ``` *When the button is pressed, the metal dome collapses, bridging the contacts (1/2 to 3/4).* --- ## 4. Typical Applications This specific part is commonly found in: 1. **Automotive:** Steering wheel controls, dashboard buttons, and key fobs. 2. **Consumer Electronics:** Power buttons on tablets or cameras. 3. **Industrial:** Reset switches on PLCs or handheld diagnostic tools. ---
