The **KWSBS-1BA-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Tactile Switch**. These components are widely used in consumer electronics, industrial controls, and medical devices due to their compact size and reliable tactile feedback. --- ### ## Technical Specifications Below are the primary electronic and physical characteristics typical for this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Push Button) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit Type** | SPST (Single Pole Single Throw) | | **Switch Function** | Off-Mom (Momentary) | | **Contact Rating** | 50mA @ 12VDC (Typical) | | **Operating Force** | 160gf to 250gf (Depending on sub-model) | | **Actuator Style** | Side Actuated / Horizontal | | **Operating Life** | 50,000 to 100,000 cycles | --- ### ### Key Electronic Features 1. **Momentary Action**: The switch remains "Closed" (conducting electricity) only as long as it is physically pressed. Once released, the internal spring returns it to the "Open" state. 2. **Tactile Feedback**: It features a "click" sensation (haptic feedback) that confirms to the user that the electrical contact has been made. 3. **Low Profile Design**: The "R" in the suffix often denotes a specific packaging (like Tape & Reel) or a side-oriented actuation, making it ideal for edge-mounting on Printed Circuit Boards (PCBs). 4. **Contact Resistance**: Designed with low initial contact resistance (usually <100mΩ) to ensure signal integrity in low-voltage logic circuits. --- ### ### Typical Pinout and Circuitry The device functions as a simple bridge. When the actuator is pressed, it connects Pin A to Pin B. ```mermaid graph LR Input[Terminal 1] --- Switch((/)) --- Output[Terminal 2] ``` ### ### Applications * **Mobile Devices**: Volume buttons or power buttons on smartphones/tablets. * **Wearables**: Function buttons on smartwatches. * **Peripherals**: Reset switches on routers or modems. * **Handheld Units**: Control buttons on medical diagnostic tools. ---
