The **M2ADS-BA11-R2** is a specific industrial control component, typically identified as a **Push Button Switch** or an **Illuminated Selector Switch** within automation and panel building. This specific part number is common in the series produced by manufacturers like **IDEC** or similar industrial hardware providers. Below is a breakdown of its electronic and mechanical specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Illuminated Push Button / Selector Switch | | **Mounting Diameter** | 22mm (Standard Industrial Size) | | **Contact Configuration** | 1NO (Normally Open) + 1NC (Normally Closed) | | **Operation Type** | Maintained (Stay-put) or Momentary (Spring Return) | | **Illumination Voltage** | Usually 12V-24V AC/DC (LED based) | | **Current Rating** | 10A (Thermal Current $I_{th}$) | | **IP Rating** | IP65 (Water and Dust Resistant) | --- ### 2. Component Breakdown The part number is modular, meaning it consists of several electronic sub-assemblies: #### A. The Contact Block This is the electrical heart of the switch. The **BA11** suffix typically denotes the contact arrangement: * **11**: Signifies one set of NO (Normally Open) and one set of NC (Normally Closed) contacts. * These are used to either complete a circuit (start a motor) or break a circuit (stop a process) simultaneously. #### B. The Operator (Head) The **M2** series usually refers to the physical interface. This part is designed for high durability, often tested for over 100,000 mechanical cycles. The **R2** suffix usually indicates the **Red** color of the lens or button. #### C. The Illumination Module Integrated behind the lens is an LED or incandescent bulb module. * **Function:** Provides visual feedback to the operator. * **Circuitry:** It is wired independently from the contact blocks so that the light can be programmed to stay on constantly or flash during a fault. --- ### 3. Connection Diagram Logic In a standard industrial control panel, the wiring for this part follows this logic: ```mermaid graph LR Power[24V DC Source] --> L1[LED Terminal +] L1 --> L2[LED Terminal -] --> Ground[0V] Control[PLC Output] --> NO_In[Contact 3] NO_In --> NO_Out[Contact 4] --> Load[Motor Starter] ``` --- ### 4. Common Applications * **Emergency Stops:** Due to the red color (R2) and NC contact availability. * **Status Indication:** Used in PLC (Programmable Logic Controller) panels to show if a machine is "Live" or in "Fault" mode. * **User Interface:** Standardized 22mm cutout makes it compatible with most industrial enclosures. ---
