The **10SP-146-R** is a specific electronic component, most commonly categorized as a **Surface Mount (SMT) Low Profile Tactile Switch**. These components are frequently used in consumer electronics, automotive interfaces, and medical devices where space is limited but user feedback is required. --- ### 1. General Specifications The "R" suffix typically denotes that the part is supplied on **Tape and Reel** for automated assembly. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount Technology (SMT/SMD) | | **Actuation Force** | Usually 160gf to 260gf (Grams-force) | | **Contact Arrangement** | SPST (Single Pole Single Throw) - Normally Open | | **Termination Style** | Gull-wing or J-bend leads | | **Operating Life** | 100,000 to 1,000,000 cycles | --- ### 2. Physical Dimensions The "146" in the part number often refers to the height or a specific series dimension. For this specific class of switch: * **Base Size:** Approximately 6mm x 6mm or 4mm x 4mm (depending on the specific manufacturer series). * **Profile:** "Low Profile" means the actuator height is kept minimal to allow for slim device designs. --- ### 3. Electrical Characteristics These switches are designed for low-power signal switching, not for direct power handling. * **Current Rating:** Typically 50mA. * **Voltage Rating:** 12V DC to 24V DC. * **Contact Resistance:** < 100mΩ. * **Insulation Resistance:** > 100MΩ at 100V DC. --- ### 4. Common Applications Due to its small footprint and reliable "click" feedback, the 10SP-146-R is used in: 1. **Consumer Electronics:** Power buttons on smartphones, volume rockers, or Bluetooth headsets. 2. **Industrial Controls:** Reset buttons on PCBs or internal configuration switches. 3. **Computing:** Mouse buttons or keyboard auxiliary keys. --- ### 5. Soldering & Manufacturing Since it is an SMT component, it is designed to withstand **Reflow Soldering** temperatures. * **Material:** High-temperature thermoplastic base. * **Plating:** Silver or Gold-plated contacts to prevent oxidation and ensure conductivity over time.
