The **M2MS-6-R/UL** is a specific type of **Micro Switch** (also known as a snap-action switch). These components are widely used in industrial and consumer electronics due to their high reliability and crisp actuation point. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical characteristics typically associated with this model: | Characteristic | Specification | | :--- | :--- | | **Switch Type** | Subminiature Snap-Action | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 5A to 10A (Model dependent) | | **Voltage Rating** | 125V / 250V AC | | **Actuator Type** | Simulated Roller Lever | | **Termination Style** | Solder Terminals / PC Pins | | **Compliance** | UL Recognized, RoHS Compliant | --- ## 2. Key Components & Construction ### A. The Housing (UL Rated) The "UL" suffix indicates that the plastic housing is made from UL-certified flame-retardant materials. This is critical for safety in high-voltage applications. ### B. Contact Mechanism * **Silver Contacts:** High-quality silver or silver-alloy contacts are used to minimize electrical resistance and prevent oxidation. * **Snap-Action Spring:** Uses a beryllium copper leaf spring to ensure that the transition between "Open" and "Closed" states is instantaneous, regardless of how fast or slow the lever is pressed. ### C. Actuator (The "6-R" Designation) * **Simulated Roller:** The "6-R" usually refers to the specific lever arm. A simulated roller is a curved metal leaf that mimics a wheel, reducing friction when the switch is triggered by a cam or a moving mechanical part. --- ## 3. Terminal Configuration As an **SPDT** switch, it features three pins: 1. **COM (Common):** The input power source. 2. **NC (Normally Closed):** Connected to COM when the lever is at rest. 3. **NO (Normally Open):** Connected to COM only when the lever is depressed. --- ## 4. Typical Applications * **Safety Interlocks:** Detecting if a door or panel is closed (e.g., microwaves or 3D printers). * **Limit Switching:** Used in CNC machines to define the "Home" position or prevent over-travel. * **Control Panels:** Acting as a high-durability push button.
