The **KWMS2-FA-R** is an industrial-grade electronic component, typically identified as a **Micro-Limit Switch** or a specific type of **Tactile/Snap-Action Switch** often utilized in automotive, industrial control, and consumer electronics. --- ## 1. Core Technical Specifications The "KWMS" series generally refers to miniature switches designed for high reliability and precise actuation. Below are the estimated technical parameters for this specific part: | Parameter | Description | Typical Value | | :--- | :--- | :--- | | **Switch Type** | Snap Action / Micro Switch | SPDT (Single Pole Double Throw) | | **Actuator Type** | Lever / Pin Plunger | Metal/Plastic | | **Current Rating** | Maximum load capacity | 2A - 5A @ 125VAC | | **Operating Force** | Pressure required to trigger | 50g - 150g | | **Mounting Type** | Terminal Style | PCB Mount (Right Angle) | | **Operating Life** | Mechanical durability | > 1,000,000 Cycles | --- ## 2. Component Breakdown The part number **KWMS2-FA-R** can be broken down into specific electronic attributes: ### A. The "KW" Series Standard designation for miniature micro-switches. These are known for their small footprint, making them ideal for space-constrained circuit boards. ### B. "2" - Rating/Size Usually denotes the physical size category or the electrical rating (e.g., 2 Amps). ### C. "FA" - Actuator Style * **F:** Often refers to the "Fixed" nature or a specific lever arm shape. * **A:** May designate the "Angle" of the terminals or the "Actuation" point. ### D. "R" - Orientation (Right Angle) The **-R** suffix is a critical electronic specification. It indicates that the pins are bent at a **90-degree angle (Right Angle)**, allowing the switch to be mounted horizontally on a vertical PCB or vice versa. --- ## 3. Circuit Application In an electronic schematic, this part functions as a physical interface between a mechanical movement and a digital signal. ```python # Logic Example: How the KWMS2-FA-R interacts with a Microcontroller if switch_signal == HIGH: stop_motor() # Often used as a limit switch print("End of travel reached.") ``` --- ## 4. Common Use Cases 1. **Industrial Automation:** Detecting the position of a moving arm. 2. **Consumer Electronics:** Power buttons or "lid closed" sensors in printers and laptops. 3. **Automotive:** Door latch sensors or seatbelt buckles. 4. **Computer Peripherals:** High-end mouse buttons or keyboard stabilizers.
