An embodiment relates to a method for closing a switch and a switch for performing the method, the switch having a stationary switch contact including a stationary contact face, a movable switch contact including a movable contact face parallel to the stationary contact face and lying under pressure against the stationary contact face in the closed state, and an elastic transversal offset of the contact faces which ensures that pressure is applied when the contact surfaces lie against each other. To guarantee closing during a short-circuit, a displaceable counter-pressure element is provided which presses against the movable contact face in the open position and at least reduces the transversal offset. The counter-pressure element moves in conjunction with the movable switch contact towards the closed position when the switch closes. The counter-pressure element stops moving during the closing movement, while the movable contact face continues to move into the closed position.

A switch includes a switch housing having a receiving space, a conductive fixed contact element and a conductive active contact element which are provided in the receiving space and being electrically connected to two terminals of the switch respectively, an actuating member reciprocating movable in a predetermined actuating direction between a rest position and an actuated position, and a conductive spring contact element movable with the actuating element. The spring contact element is in constant contact with the fixed contact element and switched between a state of being in contact with a conductive contact surface of the active contact element and a state of being disconnecting with the conductive contact surface of the active contact element. The actuating element is moved back from the actuated position to the rest position due to spring force of the spring contact element.
