The **M2SED-413-R/UL** is a specialized industrial selector switch assembly, typically manufactured by **Altech Corp**. It is part of their 22mm industrial control series, designed for rugged applications requiring manual input and status selection. ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Series** | M-Series (22mm) | | **Switch Type** | Selector Switch (Illuminated) | | **Operator Action** | Maintained (Stay-put) | | **Positions** | 2-Position (Left / Right) | | **Color** | Red (R) | | **Bezel Material** | Metal (Chrome-plated) | | **Standards/Compliance** | UL Recognized, CE, CSA | | **Protection Rating** | IP65 / NEMA 4X (Dust-tight, Water-resistant) | --- ### 2. Electronic & Structural Components The M2SED-413-R/UL is an assembly of several distinct parts that work together to provide an electrical interface: #### A. The Operator (Actuator) The top part visible to the user is the **Red knob**. Because this model is "Maintained," it stays in the position it is turned to until manually moved back. The "R" in the part number signifies the Red color, and the "413" designates the specific mechanical turning configuration. #### B. The Light Module (Illumination) As an illuminated switch, it contains a socket for a light source (usually an **LED bulb** or a neon lamp). * **Voltage Compatibility:** Depends on the specific bulb used (typically 12V, 24V, 110V, or 230V AC/DC). * **Function:** Provides visual feedback to the operator regarding the machine state. #### C. Contact Blocks While the "M2SED" prefix refers to the operator, it is used in conjunction with modular contact blocks: * **Normally Open (NO):** Closes the circuit when the switch is turned. * **Normally Closed (NC):** Opens the circuit when the switch is turned. * The modular design allows you to stack multiple contact blocks to control different electrical loads simultaneously. #### D. Mounting Bracket A metal or heavy-duty plastic yoke that secures the operator to the control panel and provides the mounting points for the contact blocks. --- ### 3. Application Use Cases This specific part is commonly found in: * **Industrial Control Panels:** To switch between "Auto" and "Manual" modes. * **Safety Systems:** As a lock-out or mode selector where visual red indication is necessary. * **Heavy Machinery:** Where IP65 protection is required against oil, water, and debris. ---
