Based on the part number **KWVS2-2BA-R**, this component is a **Miniature Vertical-Mount Tactile Switch** typically manufactured by companies like Diptronics or similar electronic component vendors. These switches are commonly used in consumer electronics, instrumentation, and control panels. --- ### 1. Technical Specifications Below are the typical technical parameters for the KWVS2 series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Through-Hole, Vertical Right Angle | | **Actuator Height** | 2.1mm (from base) | | **Operating Force** | 160gf ± 50gf (Standard) | | **Contact Rating** | 50mA, 12V DC | | **Contact Resistance** | 100mΩ Max | | **Insulation Resistance** | 100MΩ Min at 500V DC | | **Operating Life** | 50,000 to 100,000 cycles | --- ### 2. Physical Construction The "KWVS2" designation breaks down into specific physical characteristics: 1. **Vertical Orientation:** The switch is designed to be mounted perpendicular to the PCB, allowing the button to be pressed from the side (Side-actuated). 2. **Actuator Style:** Usually features a round plastic stem. 3. **Terminals:** Two or four pins depending on the specific sub-model, designed for wave soldering. 4. **Seal:** The "-R" suffix often indicates **RoHS Compliance** or specific packaging (like Reel or Bag depending on manufacturer nomenclature). --- ### 3. Application Use Cases Because of its small footprint and side-actuation, it is ideal for: * **Reset Buttons:** Located on the side of a device casing. * **Volume/Navigation:** Side buttons on handheld devices. * **Industrial Controls:** Compact interface panels. * **Consumer Electronics:** Wearables or small household appliances. --- ### 4. Circuit Diagram (Internal) The switch operates as a simple **SPST-NO** (Single Pole Single Throw - Normally Open) circuit: ```text Term 1 (Input) Term 2 (Output) o------------------/ ----------------o (Momentary Push) ```
