摘要： A bus bar of a contact device includes at least one electric path piece selected from a reverse and a forward electric path piece extending along a direction of current flowing through a moving contactor. The moving contactor is positioned between the reverse electric path piece and a fixed contact in moving directions of the moving contactor with the moving contactor positioned in the closed position. The reverse electric path piece allows current to flow therethrough in an opposite direction from current flowing through the moving contactor. The forward electric path piece is positioned on a same side as the fixed contact relative to the moving contactor in the moving directions of the moving contactor with the moving contactor positioned in the closed position. The forward electric path piece allows current to flow therethrough in a same direction as current flowing through the moving contactor.

摘要： A contact module includes a pair of contact devices, each of which includes a fixed terminal and a moving contactor. The moving contactor moves from a closed position where the moving contact is in contact with the fixed contact to an open position where the moving contact is out of contact with the fixed contact, and vice versa. One moving contactor generates, when energized, a magnetic field that applies force to the other moving contactor in a direction from the open position of the other moving contactor toward the closed position of the other moving contactor. The other moving contactor generates, when energized, a magnetic field that applies force to the one moving contactor in a direction from the open position of the one moving contactor toward the closed position of the one moving contactor.

摘要： A first conductive member is fixed to a first fixed terminal having a longitudinal direction, and a second conductive member is fixed to a second fixed terminal having a longitudinal direction. The first fixed terminal and the second fixed terminal are fixed to a partition member. A first extension portion of the first conductive member includes a first opposed portion opposed to at least one of the first fixed terminal at a first fixed contact side of the partition member. The first opposed portion extends in the longitudinal direction of the first fixed terminal.
