The **M2SES-1AA-R** belongs to a specialized category of electronic components, typically associated with **M2 series selectors or industrial switches** (often manufactured by companies like Omron or similar industrial automation brands). Below is a detailed breakdown of its specifications, construction, and technical characteristics. --- ## 1. Technical Specifications The M2SES series is generally defined by its modular design for industrial control panels. | Feature | Description | | :--- | :--- | | **Component Type** | Selector Switch / Key Selector | | **Circuitry** | SPDT (Single Pole Double Throw) or DPDT depending on contact block | | **Illumination** | Non-illuminated (Standard) | | **Mounting Type** | Panel Mount (typically 16mm or 22mm hole) | | **Terminal Style** | Solder or Tab terminals | | **Color Code** | Red (R designation) | --- ## 2. Key Electronic & Mechanical Parts ### A. The Operator (Actuator) The "head" of the component. The **-1AA** suffix usually refers to the specific physical movement: * **Maintained Action:** The switch stays in the position it is turned to. * **Angle of Throw:** Typically 90 degrees between positions. * **Bezel:** Usually round or square, made of high-grade industrial plastic or metal. ### B. The Contact Block This is the electrical portion of the assembly: * **Gold-plated or Silver contacts:** To ensure low resistance and high reliability in logic-level switching. * **Current Rating:** Typically rated for 1A to 5A at 125VAC/250VAC. ### C. Housing (Body) * **Material:** UL-rated flame-retardant polymers. * **Protection:** Often rated **IP40 or IP65**, meaning it is protected against dust and water splashes from the front of the panel. --- ## 3. Typical Applications These parts are designed for low-power control signals in automation: 1. **Industrial Control Panels:** Selecting between "Auto" and "Manual" modes. 2. **Emergency Overrides:** Restricting access to specific machine functions. 3. **Test Equipment:** Switching between different diagnostic circuits. --- ## 4. Part Number Breakdown (Generalized) While manufacturers vary slightly, the nomenclature usually follows this logic: | Prefix | Series | Action | Color | | :--- | :--- | :--- | :--- | | **M2** | Series Name | **1AA** | **R** | | Manufacturer ID | Modular Switch | Maintained, 2-position | Red Handle/Cap | ---
