The **M2PHSW-1A-R/N** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Push Button Switch**. These components are widely used in consumer electronics, automotive interfaces, and industrial controls where a tactile response is required in a compact footprint. --- ### 1. Technical Specifications Below are the general characteristics typically associated with this part number: | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch / Push Button | | **Mounting Type** | Surface Mount Technology (SMT/SMD) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Switch Function** | Momentary (Normally Open) | | **Termination Style** | Gull Wing or J-Lead | | **Actuator Type** | Horizontal / Side Actuated | | **RoHS Status** | Compliant (Lead-Free) | --- ### 2. Key Components & Materials The internal architecture of the M2PHSW-1A-R/N consists of several critical layers: * **Actuator:** The physical button pressed by the user. In the "HSW" (Horizontal Switch) series, this is often designed for side-pushing rather than top-down pressing. * **Contact Dome:** A stainless steel or copper alloy dome that provides the "click" feel (tactile feedback) and completes the electrical circuit when compressed. * **Base/Housing:** High-temperature thermoplastic (LCP or Nylon) capable of withstanding reflow soldering temperatures. * **Terminals:** Silver or gold-plated brass to ensure high conductivity and oxidation resistance. --- ### 3. Part Number Breakdown (Typical) While manufacturers vary slightly, the nomenclature usually follows this logic: 1. **M2P:** Series identifier (Miniature/Micro Push). 2. **HSW:** Horizontal Side-actuated Washable (indicates the orientation and sealing). 3. **1A:** Contact rating or specific dimension code. 4. **R/N:** Packaging or Finish (e.g., "R" for Tape & Reel, "N" for Natural/Silver finish). --- ### 4. Common Applications * **Wearables:** Power or function buttons on smartwatches. * **Handheld Devices:** Volume rockers or camera shutters on smartphones. * **Computing:** Reset switches on motherboards or peripheral input buttons. * **Automotive:** Dashboard controls or key fob buttons.
