    Classification and function of automotive relays

    Automotive relays are generally electromagnetic or solid. The electromagnetic relay says that the coil is energized to generate a magnetic field that attracts the electric shock and fits the static contact to turn on the circuit. The current mostly used in the solid state generates electrons throug... read more
