An electrical switching device including a base terminal (106) that extends substantially in an axial direction (190) and has a base contact (122). The switching device also includes a movable terminal (224) that extends substantially in the axial direction (190) and has a mating contact (120). The movable and base terminals (224, 106) extend generally parallel to each other and are separated by a field spacing (S 3 ). The movable terminal (224) is selectively movable to and from the base terminal (106) to electrically connect the base and mating contacts (122, 120) at a contact interface (234). The switching device also includes a magnetic shield (135) that is located between the movable and base terminals (224, 106) within the field spacing (S 3 ). The movable terminal (224) experiences a separation force when current (I C1 , I C2 ) flows through the base and movable terminals (224, 106) in opposite directions. The magnetic shield (135) is configured to reduce the separation force (F S ) experienced by the movable terminal (224) to facilitate maintaining the contact interface (234) between the base and mating contacts (122, 120). |
