Abstract
An electromagnetic switch including a first stationary electric contact, a second stationary electric contact, a mechanical contact, and a moveable contact. The electromagnetic switch is configured for reciprocal motion of the moveable contact into and out of contact with the first stationary electric contact and the second stationary electric contact, wherein the moveable contact remains in contact with the mechanical contact (e.g., a non-conducting contact) throughout the reciprocal motion. In various embodiments, the moveable contact is configured so that at the end of the reciprocal motion three contact points occur, and a triangle defined by the three contact points encloses a center of force of the reciprocal motion.
