吸収回路。In a surge absorption circuit that is supplied with power from a low-voltage DC power source and has a diode for preventing back electromotive force in parallel across both ends of an electrical component such as a relay or solenoid, a surge absorption element is connected in parallel to the diode to prevent interference from outside. 1. A surge absorption circuit characterized in that the diode is prevented from being destroyed by significantly attenuating an excessive surge when the contact is opened or closed.
