The **M2AMS2-1B-R/N** is a specific electronic component belonging to the **electromechanical switch** category. Specifically, it is a high-quality, miniature toggle switch often used in industrial and telecommunications applications. Below is a detailed breakdown of its technical specifications and features. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Switch Function** | On-On | | **Contact Rating** | 5A @ 120VAC / 28VDC; 2A @ 250VAC | | **Mounting Type** | Right Angle, Through-Hole (PCB Mount) | | **Actuator Style** | Standard Round Lever | | **Contact Material** | Gold or Silver Plating (suffix dependent) | | **Operating Temp** | -30°C to +85°C | --- ### Part Number Breakdown While manufacturer codes vary slightly, the "M2A" series generally follows this logic: * **M2A:** Series identifier (Miniature Toggle Switch). * **MS2:** Sub-category defining the specific physical dimensions and sealing. * **1B:** Represents the SPDT (Single Pole Double Throw) configuration with specific terminal spacing. * **R/N:** * **R:** Usually indicates the terminal orientation (Right Angle). * **N:** Often refers to specific finishes or RoHS compliance markers. --- ### Key Internal Components The switch is comprised of several critical electronic and mechanical parts: 1. **Actuator (Lever):** The physical handle used to toggle the switch. Usually made of chrome-plated brass for durability. 2. **Bushing:** The threaded or smooth neck that secures the actuator to the body. 3. **Housing (Case):** Made of Diallyl Phthalate (DAP), a high-strength, heat-resistant plastic that ensures electrical insulation. 4. **Contacts/Terminals:** These are the conductive paths. In this specific model, they are designed for PCB insertion at a 90-degree angle (Right Angle). 5. **Internal Spring Mechanism:** Provides the tactile "click" and ensures a firm electrical connection between the common pin and the selected output pin. --- ### Applications * **Telecommunications:** Network servers and switching equipment. * **Instrumentation:** Control panels and test equipment. * **Medical Equipment:** Interface controls for diagnostic devices. * **Industrial Controls:** Manual override switches on PCBs.
