The **M2AMS-161-R** is a specific electromechanical component, commonly categorized as a **Micro-Switch** or **Snap Action Switch**. These parts are designed to open or close an electrical circuit with very little physical force and high precision. Below is a detailed breakdown of the electronic and physical specifications of this component. --- ### 1. General Specifications The part is characterized by its subminiature size and the specific "R" suffix, which usually denotes the actuator type or lead configuration. | Feature | Specification | | :--- | :--- | | **Component Type** | Snap Action Micro-Switch | | **Contact Configuration** | SPDT (Single Pole Double Throw) | | **Switching Function** | On-(On) / Momentary | | **Actuator Type** | Simulated Roller Lever / Lever (Model dependent) | | **Termination Style** | PCB Terminals (Right Angle or Straight) | --- ### 2. Electrical Characteristics Understanding the electrical limits is crucial to prevent component failure or arcing. * **Current Rating:** Typically ranges from **0.1A to 3A** depending on the specific voltage (lower current for DC, higher for AC). * **Voltage Rating:** Generally rated for **125V AC** or **30V DC**. * **Contact Resistance:** Usually less than **50mΩ** (initial). * **Insulation Resistance:** Minimum of **100MΩ** at 500V DC. * **Dielectric Strength:** Often rated for **1,000V AC** for 1 minute between non-consecutive terminals. --- ### 3. Mechanical & Environmental Properties The "M2" series is known for its durability in small form factor electronics. * **Operating Force (OF):** High sensitivity, typically requiring between **25g to 150g** of force to actuate. * **Mechanical Life:** Designed for over **1,000,000 cycles**. * **Electrical Life:** Approximately **50,000 to 100,000 cycles** at full load. * **Operating Temperature:** Standard range is **-25°C to +85°C**. --- ### 4. Common Applications Due to its small size and reliability, the M2AMS-161-R is frequently used in: 1. **Computer Peripherals:** Mouse buttons or joystick triggers. 2. **Home Appliances:** Door sensors in microwaves or limit switches in printers. 3. **Industrial:** End-stop sensors for CNC machines or 3D printers. 4. **Consumer Electronics:** Power buttons that require tactile feedback. --- ### 5. Terminal Pinout (SPDT) The switch typically features three pins: 1. **COM (Common):** The input terminal. 2. **NC (Normally Closed):** Connected to COM when the lever is NOT pressed. 3. **NO (Normally Open):** Connects to COM only when the lever IS pressed.
