The part number **10MK-B6-R** typically refers to a **10mm Circular Sealed Tactile Switch** or a specific high-reliability push-button component, often manufactured by companies like **Shinmei** or similar precision electronic part suppliers. Below is a detailed breakdown of its characteristics, technical specifications, and common applications. --- ### 1. General Overview This component is a sub-miniature, momentary tactile switch. It is designed for PCB (Printed Circuit Board) mounting and is known for its "tactile" feedback—the physical "click" felt when the button is pressed. ### 2. Technical Specifications The following table outlines the standard parameters for this series: | Parameter | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Type** | Through-hole (B-type usually denotes terminal style) | | **Dimensions** | 10mm x 10mm (Base) | | **Contact Arrangement** | SPST (Single Pole, Single Throw) | | **Actuation Force** | 1.6N to 2.5N (standard "B" series) | | **Voltage Rating** | 12V DC to 24V DC | | **Current Rating** | 50mA | | **Life Cycle** | ~100,000 to 1,000,000 cycles | | **RoHS Status** | Compliant (indicated by -R) | --- ### 3. Part Number Breakdown The alphanumeric code follows a specific logic: * **10MK**: Refers to the series size (10mm body) and mechanical design. * **B**: Often designates the **Terminal Shape** or **Actuation Force**. In many catalogs, "B" indicates a straight through-hole pin configuration. * **6**: Usually represents the **Actuator Height** (e.g., 6mm from the base of the switch). * **R**: Generally stands for **RoHS Compliant** or **Tape & Reel** packaging (though for through-hole, it usually signifies environmental compliance). ### 4. Key Features * **Sealed Construction:** Many variants of the 10MK series are sealed to withstand soldering processes and cleaning solvents (IP64 or IP67 equivalent). * **Snap-in Terminals:** The pins are often shaped to hold the part in place on the PCB before the soldering process occurs. * **High Reliability:** Designed for low-current signal switching with gold or silver-plated contacts to prevent oxidation. ### 5. Common Applications Due to its small footprint and reliable feedback, it is used in: * **Industrial Controls:** Panel resets and mode selection. * **Consumer Electronics:** Microwave ovens, washing machines, and audio equipment. * **Medical Devices:** Interface buttons for handheld diagnostic tools. * **Computing:** Peripheral input buttons. ---
