Based on the technical nomenclature, the **M2CE-11-R2/N** appears to be a specific model of an industrial **Command/Signaling Device**, likely an **Illuminated Emergency Stop Switch** or a specialized **Push Button** from a manufacturer like *IDEC* or *Altech*. Below is a breakdown of the electronic and mechanical components typical for this part number. --- ### 1. Part Number Breakdown (Technical Estimation) | Segment | Component Type | Description | | :--- | :--- | :--- | | **M2CE** | Series Identifier | Modular 22mm command series (Industrial Grade). | | **11** | Contact Configuration | Typically denotes **1NO (Normally Open) + 1NC (Normally Closed)** contacts. | | **R2** | Actuator Style | Red Mushroom Head (2-position, Push-Lock/Turn-Reset). | | **SLASHN (/N)** | Special Feature | Often denotes a specific illumination voltage (e.g., Neon or LED) or a specific North American certification. | --- ### 2. Internal Electronic & Mechanical Parts An industrial switch of this type consists of three primary layers: #### A. The Actuator (Head) * **Material:** High-impact polycarbonate. * **Function:** Physical interface for the operator. In "R2" models, this is usually a locking mechanism that stays depressed until manually rotated to release. #### B. The Contact Block * **Contact Material:** Silver-alloy or gold-plated contacts to ensure low resistance. * **Circuitry:** * **Normally Closed (NC):** Used for safety/stop circuits (breaks the circuit when pressed). * **Normally Open (NO):** Used for signaling or monitoring (completes the circuit when pressed). * **Terminals:** Screw-down terminals or spring-clamp terminals for wire connection. #### C. The Illumination Module (LED/Lamp) * **Light Source:** Integrated LED or replaceable bulb. * **Voltage Regulator:** Internal resistor or transformer to handle industrial voltages (e.g., 24V AC/DC or 110V/220V AC). * **Diffuser:** Internal lens to ensure even light distribution across the red cap. --- ### 3. Technical Specifications | Feature | Typical Value | | :--- | :--- | | **Mounting Hole Diameter** | 22.5 mm | | **Rated Operational Voltage** | 250V AC/DC | | **Thermal Current (Ith)** | 10A | | **Ingress Protection** | IP65 (Dust tight, water-jet protected) | | **Mechanical Life** | > 500,000 cycles | | **Operating Temperature** | -25°C to +55°C | --- ### 4.
