The **K-62B-R** is a specific electronic component primarily recognized as a **Tactile Switch** (Push Button) manufactured by companies like **Kinghel** or similar electronic hardware suppliers. These parts are fundamental in providing user-interface feedback in consumer electronics. --- ### 1. Technical Specifications The K-62B-R belongs to the category of micro-switches. Below are the typical electronic and mechanical characteristics: | Parameter | Specification | | :--- | :--- | | **Type** | Momentary Tactile Switch | | **Mounting Type** | Through-Hole (DIP) or SMD (depending on sub-variant) | | **Dimensions** | Usually 6.0mm x 6.0mm | | **Height** | Determined by the "B" suffix (often 4.3mm to 9.5mm) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Dielectric Strength** | 250V AC for 1 minute | --- ### 2. Breakdown of the Model Name Electronic part numbers are often coded to describe physical attributes: * **K**: Often represents the manufacturer series (e.g., Kinghel). * **62**: Refers to the base size (6mm x 6mm). * **B**: Often denotes the height of the plunger (the part you press). * **R**: Usually indicates **RoHS Compliance** or specific packaging (like Tape & Reel). --- ### 3. Key Electronic Characteristics #### A. Contact Resistance The K-62B-R is designed for low-power signal switching. It typically features a contact resistance of **≤ 100mΩ**. Over time, oxidation can increase this resistance, leading to "button bounce." #### B. Tactile Feedback (The "Click") The "Tactile" part of the name refers to the metal dome inside. When pressed, the dome collapses to bridge two contacts, providing a physical "click" sensation and an audible snap. #### C. Operating Force These switches are usually rated by the force required to actuate them, measured in Gram-force (gf). Common ratings for this series are: * **160gf**: Standard soft click. * **250gf**: Firm, heavy click. --- ### 4. Circuit Diagram Representation In a schematic, the K-62B-R is represented as a simple normally-open switch: ```text [Terminal 1] ----/ ---- [Terminal 2] | (Momentary Closure) ``` --- ### 5. Common Applications * **Consumer Electronics:** Remote controls, microwave panels, and toys. * **Computing:** Reset buttons on motherboards or peripheral clicks. * **Industrial:** Interface panels for PLC controllers.
