What is impulse relay?

An impulse relay is an electromechanical switch that is activated by a brief electrical pulse, rather than a sustained voltage. It typically consists of a coil that generates a magnetic field when energized, allowing it to close or open contacts momentarily. This type of relay is commonly used in applications where a temporary action is needed, such as in lighting control systems or automation circuits. Its ability to operate with short pulses makes it efficient for energy-saving applications.
