The invention relates to a method for closing a switch (1) and a switch (1) for performing the method, the switch (1) having (a) a stationary switch contact (4) comprising a stationary contact face (4b), (b) a movable switch contact (5) comprising a movable contact face (5b) which runs parallel to the stationary contact face (4b) and lies under pressure against the stationary contact face (4b) in the closed state, and (c) an elastic transversal offset of the contact faces (4, 5) which ensures that pressure is applied when the contact surfaces (4, 5) lie against each other. In order to guarantee closing during a short-circuit, a displaceable counter-pressure element (11) is provided which presses against the movable contact face (5b) in the open position and at least reduces the transversal offset, characterised in that the counter-pressure element (11) moves in conjunction with the movable switch contact (5) towards the closed position when the switch closes and in that the counter-pressure element (11) stops moving during the closing movement, while the movable contact face (5b) continues to move into the closed position. |
