Instantaneous relays operate without intentional delay, switching contacts immediately when the coil is energized and reverting when voltage is removed. Designed for fast, reliable control in critical railway and industrial applications, these relays ensure precise signal transmission and system responsiveness. Their robust construction supports long service life in demanding environments, including vibration, temperature fluctuations, and electrical disturbances, making them ideal for safety-critical switching functions.
The BK 400 safety critical, heavy duty and weld resistant relay has 4 double make / double break C/O contacts (form Z). Weld no transfer and silver tin oxide safety contacts are
