The **M5MV-K4W-R** is a specific variant of a mechanical component, typically identified as a **Miniature Tactile Switch** or a specific type of **Micro Switch** often used in automotive and industrial control panels. Below is a breakdown of its electronic and physical specifications. --- ### 1. Technical Specifications The following table outlines the typical electrical and mechanical ratings for this component series: | Parameter | Specification | | :--- | :--- | | **Contact Type** | SPST (Single Pole Single Throw) | | **Switching Voltage** | 12V DC (Typical) | | **Switching Current** | 50mA (Typical) | | **Operating Force** | 1.6N to 2.5N (Model dependent) | | **Mounting Type** | Surface Mount (SMD) / Through-Hole | | **Terminal Type** | Gull-wing or J-bend leads | | **Lifecycle** | ~100,000 to 1,000,000 cycles | --- ### 2. Key Electronic Features * **Tactile Feedback:** This part is designed to provide a distinct "click" sensation, allowing the user to confirm the switch has been actuated electronically. * **Low Contact Resistance:** Usually rated below $100m\Omega$, ensuring minimal signal loss in low-voltage logic circuits. * **Insulation Resistance:** High resistance (often $>100M\Omega$ at 100V DC) to prevent leakage between terminals. * **Sealing (IP Rating):** The "W" in the suffix often denotes a **Waterproof** or dust-sealed design, making it suitable for harsh environments. --- ### 3. Application Use Cases Because of its small footprint and durability, it is commonly found in: 1. **Automotive Electronics:** Steering wheel buttons, key fobs, and dashboard controls. 2. **Consumer Devices:** Handheld electronics requiring compact momentary switches. 3. **Industrial Controls:** Reset buttons on PCBs and interface panels. --- ### 4. Circuit Diagram Representation In an electronic schematic, the M5MV series is represented as a simple momentary open switch: ```text (Input) ----/ ---- (Output) (Push) ```
