The **KGS1B-R/Q** is a specific electronic component typically identified as a **Miniature Toggle Switch** or a specialized **Push-button Switch** (depending on the exact series manufacturer, often associated with industrial controls or automotive grade electronics). Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. General Specifications The KGS series is designed for low-power signal switching or power-on/off applications in compact environments. | Feature | Specification (Typical) | | :--- | :--- | | **Circuit Type** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-ON or ON-(OFF) | | **Current Rating** | 1A to 3A @ 125VAC / 28VDC | | **Contact Resistance** | < 20 mΩ | | **Insulation Resistance** | > 1000 MΩ | | **Dielectric Strength** | 1,000 Vrms at sea level | | **Operating Temp** | -30°C to +85°C | ### 2. Suffix Breakdown (R/Q) The letters at the end of the part number usually denote specific material or terminal configurations: * **R (Terminal Material):** Usually indicates **Gold plating** over nickel. This is ideal for "dry circuits" (low power) because gold prevents oxidation, ensuring a reliable connection at very low voltages. * **Q (Terminal Material):** Usually indicates **Silver plating**. Silver is preferred for higher current applications as it has excellent conductivity, though it may tarnish over time if not used. * **Combination (R/Q):** Often signifies a component that meets both standards or uses silver contacts with gold flash/plating to handle a wider range of current (from logic level to power level). ### 3. Physical Construction The "1B" designation often refers to the mechanical mounting style: 1. **Body Material:** High-temperature Diallyl Phthalate (DAP) or similar UL94V-0 plastic. 2. **Actuator:** Chrome-plated brass or molded plastic. 3. **Terminals:** PC thru-hole (solder pins) or solder lugs, depending on the specific sub-variant. 4. **Bushing:** Threaded for panel mounting or unthreaded for PCB support. ### 4. Common Applications Due to its reliability and small footprint, the KGS1B-R/Q is found in: * **Telecommunications:** Network switching equipment. * **Instrumentation:** On/off toggles for handheld meters. * **Medical Equipment:** Control panels for diagnostic tools. * **Audio/Visual:** Signal routing in mixers or guitar pedals. ---
