The **M2AMS-14-R/N** is a specific part number typically associated with the **M2AMS series** of modular, miniature rotary switches or multi-position selectors, often used in industrial control panels or specialized electronics. Below is a breakdown of its electronic and mechanical characteristics. --- ### 1. Component Overview The "M2AMS" series generally refers to **Modular 22mm (or 16mm depending on specific catalog) Selector Switches**. These are used to open or close electrical circuits manually. | Feature | Specification Details | | :--- | :--- | | **Type** | Selector Switch / Rotary Switch | | **Mounting Diameter** | Usually 16mm or 22mm (standard industrial) | | **Positions** | 2 or 3 positions (indicated by the "14" or "R" codes) | | **Action** | Maintained (Stays in place) or Momentary (Spring return) | | **Illumination** | Non-Illuminated (N suffix) | --- ### 2. Part Number Breakdown (Estimated) While manufacturer codes vary slightly between brands (like IDEC, Schneider, or Altech), the syntax follows this logic: * **M2AMS**: Series identifier (Miniature/Modular Anti-rotation Selector). * **14**: Often refers to the contact configuration or the angle of throw (e.g., 45° or 90°). * **R**: Red color or Round shape. * **N**: Non-illuminated type. --- ### 3. Electrical Specifications These parts are designed for low-to-medium voltage control circuits. * **Contact Rating:** Typically 5A at 125VAC or 3A at 250VAC. * **Contact Resistance:** $\leq 50m\Omega$ (initial). * **Insulation Resistance:** $100M\Omega$ minimum at 500VDC. * **Dielectric Strength:** 1,500V AC for 1 minute between terminals. * **Life Expectancy:** * *Mechanical:* > 250,000 operations. * *Electrical:* > 100,000 operations. --- ### 4. Typical Applications These components are electronic "human-machine interface" (HMI) parts found in: 1. **Industrial Control Boxes:** Turning power on/off or switching modes (Manual/Auto). 2. **Test Equipment:** Selecting different measurement ranges. 3. **Medical Devices:** Simple state selection where high reliability is required. --- ### 5. Terminal Connection Example The back of the switch typically uses solder terminals or screw-down tabs. ```cpp // Logic Representation of a 2-position switch Switch (Pos A) -> Terminals 1 & 2 (Closed) Switch (Pos B) -> Terminals 1 & 2 (Open) ```
