The **M2AMS-15B-R/UL** is a specific electronic component typically categorized as a **Micro-switch** or **Snap Action Switch**, often used in industrial controls, home appliances, and safety mechanisms. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This switch is designed for high reliability and rapid response. The "UL" suffix indicates it meets Underwriters Laboratories safety standards. | Feature | Specification | | :--- | :--- | | **Switch Type** | Micro-switch / Snap Action | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Short Hinge Roller Lever | | **Current Rating** | 15A at 125/250VAC | | **Termination Style** | Solder or Quick Connect (depending on sub-variant) | | **Safety Certification** | UL, CSA, VDE (Regionally dependent) | --- ### 2. Key Electronic Components & Construction The internal mechanism of the M2AMS-15B-R/UL consists of several critical parts: * **Contacts:** Usually made of silver alloy to handle the 15A current load while preventing oxidation and ensuring low contact resistance. * **Snap-Action Spring:** A high-precision beryllium copper or stainless steel spring that ensures the "snap" movement, providing instantaneous switching regardless of the speed of the external actuator. * **Case Material:** High-grade phenolic or thermoplastic resin, providing excellent electrical insulation and high heat resistance. * **The Roller Lever:** A mechanical interface that reduces friction when the switch is triggered by a rotating cam or a sliding object. --- ### 3. Electrical Performance Data | Parameter | Value | | :--- | :--- | | **Contact Resistance** | Max 15 mΩ (Initial) | | **Insulation Resistance** | Min 100 MΩ (at 500VDC) | | **Dielectric Strength** | 1,000VAC for 1 minute (between contacts) | | **Mechanical Life** | Up to 10,000,000 cycles | | **Electrical Life** | Up to 100,000 cycles (at full load) | --- ### 4. Common Applications Due to its high current rating and roller lever design, this part is commonly found in: 1. **Safety Interlocks:** Detecting if a door or panel is closed (e.g., microwave doors). 2. **Limit Switches:** Preventing mechanical over-travel in CNC machines or 3D printers. 3. **Industrial Automation:** Conveyor belt sensing and position detection.
