Abstract
A relay assembly includes a coil and a stationary contact having a first contact surface. At least a portion of the first contact surface defines a wiping contact surface. The relay assembly also includes a movable contact having a second contact surface defining a contact area that engages the first contact surface. The movable contact is moved along a driving path toward the stationary contact when current is passed through the coil, and the movable contact is moved along a rebound path different from the driving path after initial impact with the stationary contact. The stationary contact is oriented or shaped with respect to the movable contact such that the movable contact engages, and wipes against, at least a portion of the wiping contact surface when the movable contact is moved along the rebound path.
