The **M2ADS-A11-R** is an industrial-grade selector switch belonging to the **M22 series** (specifically the 22.5mm mounting diameter family). These components are widely used in control panels for manual human-machine interface (HMI) operations. Below is a breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The device is characterized by its mounting size and its "non-illuminated" status. | Property | Description | | :--- | :--- | | **Manufacturer** | Often associated with Eaton (Moeller) or similar industrial standards | | **Series** | M22 (22.5mm standard) | | **Actuator Type** | Selector Switch (Short Thumb-grip) | | **Positions** | 2-Position (Usually 0 and 1) | | **Switching Angle** | 60° (Standard for 2-position) | | **Illumination** | Non-Illuminated | --- ### 2. Physical & Material Composition The "A11" designation often refers to the specific configuration of the contact blocks or the mechanical action. * **Bezel Material:** Usually Titanium or High-grade Plastic (Silver/Grey finish). * **IP Rating:** Typically **IP66**, meaning it is dust-tight and protected against powerful water jets. * **Mounting Hole:** 22.5 mm standard industrial cutout. * **Action:** Stay-put (Maintained). When turned to a position, it stays there until manually turned back. --- ### 3. Electronic Contact Blocks While the M2ADS-A11-R refers to the **actuator** (the part you touch), it must be paired with contact blocks to function electrically. * **Standard Configuration:** Usually paired with 1 NO (Normally Open) and 1 NC (Normally Closed) contact block. * **Voltage Rating:** Typically rated up to **500V AC** depending on the attached contact block. * **Current Rating (Thermal):** Generally **10A** (Ith). * **Service Life:** Mechanical lifespan is typically > 1,000,000 operations. --- ### 4. Wiring Diagram (Conceptual) The switch acts as a bridge in a control circuit. Below is a simple representation of how the internal contacts operate during rotation: ```mermaid graph LR A[Position 0 / OFF] -->|Rotate 60°| B[Position 1 / ON] subgraph Contact State C[NO Contact: Open] D[NC Contact: Closed] end ``` ### 5. Application Examples 1. **Power Toggle:** Turning a machine's control power on or off. 2. **Mode Selection:** Switching a system between "Manual" and "Auto" modes. 3. **Safety Interlocks:** Ensuring a circuit is physically broken before maintenance. ---
