Abstract: A contact assembly (1) configured for a load break switch (7), a load break switch (7) including the contact assembly (1), and a method for closing a circuit path of a contact assembly (1). The contact assembly (1) includes a stationary contact unit (10) and a movable contact unit (20), wherein
the movable contact unit (20) is configured to move between an open position and a closed position via an intermediate position, and
the stationary contact unit (10) is configured, in the intermediate position or closed position, to generate an electromagnetic closing force (50) acting on the movable contact unit (20) with the electromagnetic closing force (50) being directed at least partly in the direction of the closed position.
