The **KWSBS-2CC-R/Q** is a specific part number typically associated with professional-grade, miniature **Snap-Action Switches** (often referred to as Microswitches). These components are designed for high reliability in detecting physical position or providing a tactile interface. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Snap-Action Microswitch | | **Contact Configuration** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 0.1A to 3A (depending on voltage) | | **Voltage Rating** | 125V AC / 30V DC (Standard range) | | **Actuator Type** | Simulated Roller Lever / Short Lever | | **Termination Style** | PCB Terminals (Right/Left Angle or Straight) | | **Mechanical Life** | > 1,000,000 cycles | --- ### 2. Functional Components * **Internal Snap Mechanism:** Uses a spring-loaded "over-center" mechanism. When a specific physical force is applied, the contacts "snap" between the Normally Closed (NC) and Normally Open (NO) positions with high speed, regardless of the speed of the physical actuation. * **Contact Material:** Usually Silver-plated or Gold-plated alloy to ensure low contact resistance and prevent oxidation over time. * **Housing (Casing):** Constructed from high-temperature thermoplastic (PBT or PPS) to withstand soldering heat and environmental stress. --- ### 3. Part Number Suffix Breakdown (R/Q) In this series, the suffixes denote specific physical configurations: 1. **-R/Q:** Often refers to the **Terminal Orientation**. * **Q:** Generally indicates Quick Connect or specific PCB footprint spacing. * **R:** Usually indicates the orientation of the lever or the right-angle bend of the pins for side-mounting on a circuit board. --- ### 4. Common Applications These parts are integrated into electronic systems where precise detection is required: * **Consumer Electronics:** Detecting if a printer tray is closed or a camera lens is in position. * **Industrial:** Limit switches for small robotic arms or CNC calibration. * **Automotive:** Door latch sensors or seatbelt buckle detection. * **Safety:** Interlock switches that cut power when a device cover is removed. --- ### 5.
