The **M2MS-6-R/N** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Micro Switch** or a tactile switch, often used in consumer electronics and industrial interfaces. Below is a detailed breakdown of its technical specifications, construction, and functionality. ### 1. General Specifications | Feature | Details | | :--- | :--- | | **Part Number** | M2MS-6-R/N | | **Switch Type** | Micro Tactile Switch | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Actuator Height** | 6.0mm (standard for the -6 suffix) | | **Operating Force** | Typically 160gf to 250gf | | **Contact Material** | Silver Plated (Standard) | --- ### 2. Physical Construction The part is designed for automated assembly processes. Its construction consists of four primary layers: 1. **Actuator (Stem):** The "button" part of the switch. The height is indicated by the "6", standing for **6.0mm**. 2. **Contact Dome:** A stainless steel or phosphor bronze dome that provides the tactile "click" feedback and completes the circuit when depressed. 3. **Housing:** Heat-resistant thermoplastic (LCP or Nylon) capable of withstanding lead-free reflow soldering temperatures. 4. **Terminals:** Metal leads extending from the base, designed to be soldered directly onto the PCB surface. --- ### 3. Suffix Meaning (R/N) In the context of micro-switches, these suffixes usually refer to packaging and environmental ratings: * **R (Tape & Reel):** Indicates that the parts are packaged in embossed carrier tape for use with high-speed "Pick and Place" assembly machines. * **N (Non-Washable/Normal):** Usually indicates the seal type. "N" typically means the switch is not hermetically sealed and should not be subjected to aqueous cleaning (water washing) after soldering. --- ### 4. Electrical Characteristics These switches are designed for low-power signal switching, not for driving heavy loads. ```cpp // Typical Electrical Limits Max_Voltage = "12V DC"; Max_Current = "50mA"; Contact_Resistance = "< 100mΩ"; Insulation_Resistance = "> 100MΩ (at 100V DC)"; Dielectric_Strength = "250V AC for 1 minute"; ``` --- ### 5. Common Applications * **Consumer Electronics:** Volume buttons on tablets, power buttons on small appliances. * **Medical Devices:** Control panels for portable diagnostic equipment. * **Industrial:** Reset switches on PCB motherboards or interface modules. * **Computer Peripherals:** Mouse buttons or keyboard function keys.
