The **M2AS1-A243-R2/N** is a specific part number typically associated with **M2 Series Industrial Micro-switches** or similar electromechanical components (often produced by brands like Highly or specialized industrial relay/switch manufacturers). Based on the alphanumeric coding common in industrial electronics, here is the breakdown of its components and technical characteristics. --- ### 1. Technical Specifications Table | Feature | Specification Details | | :--- | :--- | | **Component Type** | Electromechanical Snap-Action Micro-switch | | **Actuator Type** | Standard Pin Plunger (S1 series style) | | **Contact Configuration** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 5A to 10A (Depending on AC/DC voltage) | | **Voltage Rating** | 125V / 250V AC | | **Terminal Type** | Solder or Quick Connect (denoted by R2/N variants) | | **Operating Force** | Medium-to-High precision snap action | --- ### 2. Part Number Breakdown The suffixing in industrial switches follows a modular logic: * **M2**: Refers to the physical frame size (Miniature size). * **AS1**: Indicates the internal mechanism and terminal orientation (Straight/Standard). * **A**: Contact Material (Usually Silver alloy for high conductivity). * **243**: Specific mechanical dimensions or customized lever length. * **R2**: Refers to the terminal shape (often Right-angle or specific PCB mounting pins). * **N**: Typically signifies "Neutral" or a specific material compliance (like RoHS/Non-flammable casing). --- ### 3. Internal Electronic Construction An electronic part of this nature consists of three primary internal zones: 1. **The Contact Block:** Uses a "snap-action" spring mechanism. This ensures that the transition between NO (Normally Open) and NC (Normally Closed) happens instantly, preventing electrical arcing that can damage circuits. 2. **The Housing:** Constructed from high-grade Thermoplastic (PBT or Phenolic), designed to withstand high temperatures and provide electrical insulation. 3. **The Terminals:** Usually copper with silver or gold plating to ensure low contact resistance and high reliability in signal transmission. ### 4. Common Applications * **Industrial Automation:** Limit sensing in conveyor belts or CNC machines. * **Home Appliances:** Door interlocks for microwaves or washing machines. * **Safety Interlocks:** Emergency stop triggers or panel detection switches. ---
