The **KLS-15-1-R** is a specific electronic component, typically categorized as a **Surface Mount Device (SMD) Tactile Switch**. These switches are designed for low-power signal switching in consumer electronics and industrial control panels. ### 1. Key Technical Specifications The following table outlines the typical electrical and physical parameters for the KLS-15-1-R series: | Feature | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit Type** | SPST (Single Pole, Single Throw) | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ (100V DC) | | **Operating Force** | 160gf / 250gf (Common variations) | | **Travel** | 0.25mm ± 0.1mm | | **Durability** | 100,000 cycles (Typical) | --- ### 2. Physical Construction The part is engineered for automated assembly and durability. Its internal architecture includes: 1. **Actuator (Button):** Usually made of high-temperature plastic (LCP or Nylon) to withstand reflow soldering. 2. **Contact Dome:** A stainless steel or copper alloy disc that provides tactile feedback ("click") and completes the electrical circuit. 3. **Terminals:** Silver-plated brass or copper for high conductivity and easy soldering. 4. **Cover:** Metal plate (often stainless steel) that secures the internal components. --- ### 3. Application Use Cases This component is widely used in devices where space is limited and a tactile user response is required: * **Consumer Electronics:** Remote controls, digital cameras, and handheld gaming consoles. * **Computer Peripherals:** Power buttons on laptops or reset buttons on networking gear. * **Medical Devices:** Control interfaces for portable diagnostic tools. * **Automotive:** Dashboard controls and keyless entry fobs. --- ### 4. Footprint and Soldering When designing a PCB for this part, engineers must follow the SMT land pattern. A typical code snippet for a PCB footprint definition (e.g., in a script-based CAD tool) might look like this: ```markdown # Example SMD Pad dimensions (in mm) Pad_Width: 1.5 Pad_Length: 2.1 Spacing_Between_Pads: 4.5 ``` ---
