Abstract
A high-durability electrical contact structure may include a first contact and a second contact disposed to face each other while being spaced apart a predetermined distance from each other. A portion of the second contact includes a magnetic material. Damage to the surfaces of an arcing electrical contact according to arc generation positions between contacts is minimized, increasing the life of the arcing electrical contact.
