Description
The KDC-21 Rocker Switch (MPN: KDC-21) is a robust, high-performance power switching component designed to provide secure and consistent control for a wide array of electrical systems. Engineered for versatility, this switch supports a 250V AC rating and offers flexible current options (3A, 6A, or 15A), making it highly adaptable for both light-duty signal circuits and more demanding power-load applications.
Built for resilience, the KDC-21 operates reliably across a broad temperature range of -25°C to 85°C. It is characterized by excellent electrical performance, featuring very low contact resistance (≤0.02Ω) and high insulation resistance (≥100MΩ) to ensure efficient power transmission and safety. With a robust design tested for over 10,000 operational cycles, the KDC-21 is a proven choice for maintaining consistent performance in diverse professional and consumer electrical environments.
