The **M6SXAT-3-R** is a specific surface-mount electronic component, typically categorized as a **Micro-Miniature Tactile Switch**. These components are widely used in consumer electronics for user interface buttons that provide physical feedback (a "click") when pressed. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the M6SXAT-3-R: | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Actuator Style** | Standard Round Button | | **Operating Force** | Typically 160gf to 260gf (varies by sub-series) | | **Contact Rating** | 50mA @ 12V DC (Standard) | | **Travel Distance** | ~0.25 mm | | **Operating Life** | 100,000 to 500,000 cycles | | **Orientation** | Top Actuated | --- ### 2. Physical Construction The part is designed for high-density PCB layouts. Its construction consists of several layers: 1. **Actuator:** The top button part that the user presses. 2. **Cover:** A metal or plastic shield that holds the internal components together. 3. **Contact Dome:** A stainless steel or phosphor bronze "snap" dome. This is the heart of the switch; it provides the tactile feel and completes the circuit when depressed. 4. **Base:** A high-temperature thermoplastic (usually LCP) capable of withstanding lead-free reflow soldering temperatures. 5. **Terminals:** Silver-plated or gold-plated leads for electrical connection to the PCB. --- ### 3. Common Applications Due to its small footprint and reliability, the M6SXAT-3-R is found in: * **Wearables:** Smartwatches and fitness trackers. * **Portable Electronics:** MP3 players, cameras, and handheld gaming devices. * **Medical Devices:** Portable monitors and diagnostic tools. * **Industrial:** Interface buttons on control panels where space is limited. --- ### 4. Typical Circuit Diagram Tactile switches are usually "Normally Open" (SPST-NO). Below is a simple representation of how it is integrated into a digital circuit: ```text VCC (3.3V/5V) | [ R ] <-- Pull-up Resistor | +------- Digital Input Pin (MCU) | [ Switch ] (M6SXAT-3-R) | GND ``` ---
