The **M2AS1-4244-R/CE** is a specific technical designation for an industrial-grade **Spring-Return Selector Switch**, typically manufactured by companies like **Altech Corp** or similar industrial control component providers. These components are essential in control panels for manual human-machine interface (HMI) operations. --- ### 1. Technical Specifications Table | Parameter | Specification | | :--- | :--- | | **Component Type** | Selector Switch (Non-Illuminated) | | **Actuator Style** | Standard Knob / Lever | | **Operation Type** | Spring Return (Momentary) | | **Mounting Diameter** | 22.5 mm (Standard Industrial size) | | **Contact Block Configuration** | 4 Normally Open (NO) / 4 Normally Closed (NC) - *Varies by sub-assembly* | | **Bezel Material** | Chrome/Metallic or High-Durability Plastic | | **Environmental Rating** | IP65 / NEMA 4X (Water and Dust resistant) | --- ### 2. Breakdown of the Model Code While naming conventions can vary slightly by manufacturer, the "4244" and suffix "R/CE" generally indicate the following: * **M2AS1:** The series designation for a 22mm metallic or heavy-duty plastic selector switch. * **4244:** This numeric sequence usually defines the **Switching Angle** (e.g., 45° or 90°) and the **Position Logic** (2-position vs 3-position). * **R:** Denotes "Spring Return." Unlike a maintained switch that stays where you turn it, this switch snaps back to the center/original position when released. * **CE:** Certification marking, indicating compliance with European Union health, safety, and environmental protection standards. --- ### 3. Electrical Functionality The device acts as a manual trigger for electrical circuits. In an industrial environment, it is commonly used for: 1. **Jogging:** Briefly moving a motor or actuator. 2. **Resetting:** Sending a momentary signal to clear a system fault. 3. **Mode Selection:** Temporarily overriding an automatic process. --- ### 4.
