Based on your inquiry, the **KWSBS-2BB-R** is a specific model within a series of **Tactile Switches** (often referred to as tact switches). These are commonly used as input buttons in consumer electronics, automotive controls, and industrial interfaces. --- ### Technical Specifications The "KWSBS" series typically features a side-actuated design. Below is a breakdown of the electronic and mechanical characteristics: | Property | Description | | :--- | :--- | | **Component Type** | Tactile Switch (Push Button) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Orientation** | Right Angle (Side Actuated) | | **Circuitry** | SPST - NO (Single Pole Single Throw - Normally Open) | | **Contact Rating** | Typically 50mA @ 12VDC | | **Operating Force** | Usually 160gf to 250gf (grams-force) | | **Travel** | ~0.25mm | | **Color/Finish** | Black body, typically with a Red (R) actuator or packaging indicator | --- ### Part Number Breakdown While manufacturer codes vary slightly, the nomenclature usually follows this logic: 1. **KWSBS**: The Series prefix (indicating a small-form-factor side-push switch). 2. **2**: Often refers to the physical dimensions or specific height profile. 3. **BB**: Typically refers to the terminal plating or base material (e.g., Brass/Bronze with Silver or Gold plating). 4. **R**: Generally stands for **Tape & Reel** packaging (for automated assembly) or designates a **Red** actuator button. --- ### Key Features and Applications #### 1. Mechanical Robustness These switches are designed for a high lifecycle (often 50,000 to 100,000 cycles). The "Right Angle" design allows the button to be pressed from the edge of a PCB, which is ideal for side-mounted buttons on devices like smartphones or remote controls. #### 2. Electronic Feedback As a tactile switch, it provides "clicky" physical feedback to the user, ensuring they know the contact has been bridged electrically. #### 3. Common Uses * **Consumer Electronics:** Volume buttons, power switches on handheld devices. * **Wearables:** Side buttons on smartwatches or fitness trackers. * **Automotive:** Dash buttons or steering wheel controls. --- ### Electrical Circuit Diagram In its default state, the circuit is open. When pressed, the internal dome collapses to connect the two terminals. ```text [ Terminal 1 ] | -------/ ------- (Switch Open) | [ Terminal 2 ] ```
