The **M2CE-11-R/CE** is a specific part number belonging to the **M2CE series** of industrial control switches, typically manufactured by companies like **OMRON**. This specific model is a **square-type, non-lighted pushbutton switch**. Below is a detailed breakdown of its electronic and physical components. --- ### 1. Technical Specifications The electrical characteristics define how the switch integrates into a circuit. | Feature | Specification | | :--- | :--- | | **Contact Configuration** | DPDT (Double Pole Double Throw) | | **Operation Type** | Alternate (Push-ON / Push-OFF) | | **Current Rating** | 5A at 125 VAC / 3A at 250 VAC | | **Voltage Rating** | 125VAC / 250VAC / 30VDC | | **Illumination** | Non-lighted | | **Button Color** | Red (indicated by the "-R" suffix) | | **Terminal Type** | Solder terminals | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps identify the specific electronic behavior of the unit: * **M2C**: Refers to the series (Square body, usually 18mm or 24mm size). * **E**: Indicates the "Electronic" or specific housing style. * **11**: Denotes the contact block configuration (DPDT). * **R**: Denotes the color of the actuator (Red). * **CE**: Indicates compliance with European safety standards (Conformité Européenne). --- ### 3. Key Electronic Components #### A. Contact Mechanism (DPDT) The internal switching mechanism is **Double Pole Double Throw**. This means it can control two separate circuits simultaneously. Each "pole" has a common terminal, a Normally Open (NO) terminal, and a Normally Closed (NC) terminal. #### B. Alternate Action (Latching) Unlike a momentary switch (which springs back immediately), the **Alternate** action means that when you press the button, it locks into position (completing the circuit) and stays there until you press it a second time to release it. #### C. Microswitch Unit The core of the M2CE-11 is a high-precision microswitch. It is designed for high reliability with silver-plated contacts to minimize electrical resistance and prevent oxidation over long periods of use. #### D. Dielectric Strength These parts are typically rated for a dielectric strength of **2,000 VAC (50/60 Hz for 1 minute)** between terminals of the same polarity, ensuring safety against high-voltage spikes in industrial environments. --- ### 4. Application Areas Because of its DPDT configuration and latching mechanism, it is commonly used in: 1. **Control Panels:** Main power toggles for sub-systems. 2. **Safety Interlocks:** Ensuring a system remains "OFF" until manually engaged. 3. **Industrial Automation:** Relaying signals to PLC (Programmable Logic Controller) inputs.
