## Overview of KWSBS-2CC-R The **KWSBS-2CC-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Tactile Switch**. It is widely used in consumer electronics for user interface applications where a small footprint and tactile feedback are required. --- ### 1. Key Technical Specifications Below is a breakdown of the typical electronic and mechanical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Push Button) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Circuit Configuration** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Current Rating** | Usually 50mA | | **Voltage Rating** | 12V DC | | **Actuation Force** | Typically 160gf to 240gf (depending on specific batch) | | **Operating Life** | 50,000 to 100,000 cycles | --- ### 2. Physical Construction The "2CC-R" designation often refers to the specific physical dimensions and the packaging (Tape and Reel). * **Compact Footprint:** Designed for high-density PCB layouts. * **Terminals:** Metal alloy with silver or gold plating to ensure high conductivity and oxidation resistance. * **Actuator:** A small plastic plunger that provides the "click" feel (tactile feedback). * **Base/Housing:** High-temperature resistant thermoplastic (LCP or Nylon) capable of withstanding reflow soldering temperatures. --- ### 3. Electronic Functionality The switch operates on a simple momentary contact principle: 1. **Rest State:** The circuit is "Open" (no current flows). 2. **Actuated State:** When the button is pressed, an internal metal dome collapses, bridging the two internal contacts. 3. **Return:** Once the pressure is released, the dome snaps back to its original shape, breaking the circuit. --- ### 4. Common Applications Due to its small size and reliability, the KWSBS-2CC-R is frequently found in: * **Wearable Technology:** Smartwatches and fitness trackers. * **Mobile Devices:** Volume or power buttons in smartphones/tablets. * **Peripherals:** Computer mice, remote controls, and handheld gaming consoles. * **Industrial:** Small reset buttons on PCB boards. --- ### 5. Soldering and Integration ```markdown ### Reflow Soldering Profile (General) - Pre-heat: 150°C to 200°C (60-120 seconds) - Peak Temperature: 260°C (max 5-10 seconds) - Cooling: Natural or forced air ``` *Note: Always consult the specific manufacturer's datasheet (e.g., Kingbright, Mitsumi, or specific regional brands) as small variations in force and height may exist depending on the exact brand of the KWSBS series.*
