The **M5MV-K0-R** is a specific electronic component, primarily recognized as a **Tactile Switch** manufactured by **C&K** (now part of Littelfuse). These switches are designed for interface applications where a small footprint and high reliability are required. --- ### 1. General Specifications The M5MV series belongs to the family of ultra-miniature, SMT (Surface Mount Technology) tactile switches. | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Pushbutton) | | **Mounting Type** | SMT (Surface Mount) | | **Actuator Type** | Round Button (Vertical) | | **Contact Arrangement** | SPST-NO (Single Pole Single Throw, Normally Open) | | **Switching Power** | Typically 1 VA | | **Operating Force** | 1.6 N (160 gf) to 2.5 N depending on specific variation | | **Operating Life** | ~100,000 to 1,000,000 cycles | --- ### 2. Physical and Mechanical Characteristics The "K0" and "R" in the part number often refer to specific mechanical attributes and packaging: * **Compact Dimensions:** Designed for high-density PCB layouts, often used in handheld devices. * **Sealing:** These parts are often categorized by their IP (Ingress Protection) rating, making them resistant to dust and moisture during the soldering process. * **Tactile Feedback:** Provides a distinct "click" sensation to the user, confirming that the circuit has been closed. * **R (Suffix):** Usually indicates **Tape and Reel** packaging, which is standard for automated pick-and-place assembly machines. --- ### 3. Electrical Characteristics Despite their small size, these switches are engineered for precision electrical signals rather than high power. * **Maximum Voltage:** 32 VDC (typical) * **Maximum Current:** 50 mA * **Contact Resistance:** < 100 mΩ * **Insulation Resistance:** > 1,000 MΩ --- ### 4. Common Applications Due to its reliability and small SMT form factor, the M5MV-K0-R is found in: * **Consumer Electronics:** Remote controls, cameras, and wearable devices. * **Industrial:** Interface panels and reset buttons on PCBs. * **Medical:** Handheld diagnostic tools. * **Automotive:** Interior controls and key fobs. ---
