The **M2TT-NE-R2/BL** is a specific part number belonging to a series of industrial-grade pushbutton switches, typically manufactured by companies like **IDEC** or similar automation component providers. This specific model belongs to the **M2 series** of miniature control units. ### 1. Technical Specifications Below are the primary electronic and mechanical characteristics of the M2TT-NE-R2/BL: | Feature | Specification | | :--- | :--- | | **Series** | M2 Series (Miniature Control Unit) | | **Contact Configuration** | DPDT (Double Pole Double Throw) | | **Action Type** | Maintained (Stay-put / Latching) | | **Illumination** | Non-Illuminated | | **Operator Shape** | Round / Mushroom Head (Large) | | **Color** | Black (BL suffix) | | **Mounting Hole** | 22mm or 30mm (Depending on adapter) | | **Terminal Type** | Solder/Tab Terminal | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's construction: * **M2**: The series identifier (Miniature 12mm or 16mm base units, often adapted for larger industrial holes). * **TT**: Designates the operator style (often indicates a "Toggle" or "Toggle-Push" mechanical action). * **NE**: Refers to the contact block housing and insulation rating. * **R2**: Specifies the contact arrangement (2 poles / DPDT). * **BL**: Color code for **Black**. --- ### 3. Electronic Functionality The device acts as a manual interface for control circuits. Because it is a **DPDT** switch, it can control two separate circuits simultaneously. * **Switching Capacity:** Usually rated for low-level signals up to 3A or 5A at 125V/250V AC (check specific datasheet for DC ratings). * **Maintained Action:** When pressed, the switch stays in the "on" position until pressed again to release. This is ideal for power-on functions rather than momentary signaling. * **Contact Reliability:** Features silver contacts (often gold-clad) to ensure low contact resistance and high reliability in industrial environments. --- ### 4. Applications The M2TT-NE-R2/BL is commonly used in: 1. **Control Panels:** For manual system overrides or mode selection. 2. **Industrial Machinery:** Where a robust, physical "latching" switch is required. 3. **Test Equipment:** For switching between different signal paths in a circuit.
