The part number **48SV2-RV5ST-R** corresponds to a specialized electronic component, typically identified as a **tactile switch** or a specific type of **miniature slide switch** used in consumer electronics, often manufactured by companies like Mitsumi or similar specialist vendors. ### 1. Component Overview This component is an electromechanical switch designed for low-power signal switching. It is characterized by its compact form factor and surface-mount (SMD) design. | Feature | Specification | | :--- | :--- | | **Type** | Tactile / Slide / Multi-function Switch | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Orientation** | Right Angle (Side-actuated) | | **Contact Rating** | Usually 1mA to 50mA @ 5V - 12V DC | | **Lifecycle** | 50,000 to 100,000 cycles | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown While specific manufacturers use proprietary codes, the nomenclature for this series generally follows this logic: * **48SV2**: Represents the series family (compact signal switches). * **RV**: Often denotes "Reverse" or a specific lever/actuator orientation (Right Vertical). * **5ST**: Refers to the physical dimensions of the actuator and the terminal pitch (5mm/Standard). * **-R**: Indicates **RoHS compliance** and/or **Tape & Reel** packaging for automated assembly. --- ### 3. Key Technical Characteristics #### Electrical Properties * **Contact Resistance:** Typically < 100 mΩ. * **Insulation Resistance:** > 100 MΩ at 100V DC. * **Dielectric Strength:** Capable of withstanding 100V AC for 1 minute. #### Mechanical Properties * **Actuation Force:** Usually light (1.0N to 2.5N) to provide tactile feedback without requiring high pressure. * **Travel Distance:** Short travel (0.15mm to 2.5mm depending on whether it is a momentary push or a slide). * **Housing:** High-temperature thermoplastic capable of withstanding reflow soldering temperatures (up to 260°C). --- ### 4. Common Applications Due to its small footprint and right-angle actuation, this part is commonly found in: 1. **Handheld Devices:** Volume or power buttons on older MP3 players or specialized medical handhelds. 2. **Digital Cameras:** Menu navigation switches or zoom toggles. 3. **Wearables:** Compact interface buttons for smartwatches or fitness trackers. 4. **IoT Modules:** Reset or configuration buttons on PCB edges. ---
