The **ME14XBG-R** is a specific electronic component, typically identified as a **Micro-Switch** or **Snap-Action Switch** manufactured by companies like **Zippy Technology Corp** (often used in automotive, industrial, and consumer electronics). Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Technical Specifications These parameters define the electrical limits and physical behavior of the switch. | Feature | Specification (Typical) | | :--- | :--- | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | 0.1A to 10.1A (Depending on voltage) | | **Voltage Rating** | 125 / 250 VAC | | **Operating Force** | ~150g - 200g (Varies by sub-model) | | **Terminal Type** | PCB Terminals / Solder Lug | | **Contact Resistance** | < 100 mΩ (Initial) | | **Insulation Resistance** | > 100 MΩ (500V DC) | --- ## 2. Key Electronic Parts & Construction The ME14XBG-R consists of several internal components that facilitate its "Snap-Action" mechanism: ### A. Contact System * **Stationary Contacts:** Fixed points (Common, Normally Open, Normally Closed). * **Movable Contact:** A spring-loaded arm that "snaps" between the fixed contacts when the actuator is pressed. * **Material:** Usually silver alloy or gold-plated (for low-current signals) to ensure high conductivity and oxidation resistance. ### B. Actuator (The "BG" Designation) * The "BG" in the part number often refers to the **Lever Type**. * It typically features a **Simulated Roller Lever** or a **Short Hinge Lever**, which reduces the physical force required to trigger the electrical connection. ### C. Internal Spring Mechanism * Utilizes a high-precision beryllium copper or stainless steel spring. This provides the "tactile click" and ensures the switch returns to its original state once pressure is released. --- ## 3. Terminal Configuration The ME14XBG-R usually follows the standard 3-pin layout: 1. **COM (Common):** The input terminal. 2. **NO (Normally Open):** The circuit is open until the lever is pressed. 3. **NC (Normally Closed):** The circuit is closed until the lever is pressed. --- ## 4. Common Applications Due to its reliability and precise travel distance, this part is commonly found in: * **Automotive:** Door latch sensing, seatbelt detection. * **Appliances:** Microwave door interlocks, vacuum cleaner power triggers. * **Industrial:** Limit switches for CNC machines or 3D printers. ---
