The **M2AMS2-1C-R2** is a specific electronic component typically identified as a **Miniature Snap-Action Micro Switch**. These parts are widely used in industrial controls, automotive electronics, and consumer appliances due to their reliability and tactile feedback. --- ## 1. Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the switch: | Parameter | Specification | | :--- | :--- | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Switching Type** | Momentary (Snap-Action) | | **Current Rating** | Typically 3A to 5A (depending on voltage) | | **Voltage Rating** | 125V AC / 250V AC | | **Actuator Type** | Simulated Roller Lever / Short Lever | | **Termination Style** | PCB Terminals (Right-Angle / R2 orientation) | | **Operating Force** | Medium (approx. 100g - 150g) | --- ## 2. Component Breakdown The part number suffix and prefix provide specific details about its physical construction: ### A. Contact Configuration (1C) The "1C" designation refers to a **Changeover contact (SPDT)**. - **COM (Common):** The input terminal. - **NO (Normally Open):** The circuit is completed only when the lever is pressed. - **NC (Normally Closed):** The circuit is completed when the switch is at rest. ### B. Terminal Orientation (R2) The "R2" suffix usually indicates a specific **PCB mounting orientation**. In many manufacturer catalogs, R2 signifies a **Right-Angle terminal** configuration where the pins are bent to one side, allowing the switch to be mounted vertically on a horizontal PCB. ### C. The Snap-Action Mechanism This part utilizes a "Spring and Plunger" system. When the actuator reaches a specific "trip point," the internal contacts snap from the NC position to the NO position almost instantaneously, regardless of the speed of the external physical movement. This prevents electrical arcing and ensures a consistent signal. --- ## 3. Common Applications Due to its small footprint and precise actuation, this part is commonly used in: 1. **Safety Interlocks:** Detecting if a door or panel is closed (e.g., microwave doors). 2. **Limit Switches:** Detecting the end of travel in a mechanical arm or 3D printer axis. 3. **User Interface:** Buttons for industrial control panels where a "click" feel is required. 4. **Sensors:** Detecting the presence or absence of an object in a feeder mechanism. --- ## 4.
