An electrical switch for interrupting a current path, in particular of a voltage supply in a motor vehicle is disclosed. The switch includes a contact point which is formed from a first contact piece and a second contact piece which is mounted such that it can move about a rotation axis. Here, the contact point is electrically closed when the two contact pieces are in contact and is electrically opened when the two contact pieces are not in contact. Furthermore, the electrical switch includes an actuator unit and an electrically non-conductive separating element which can be moved in a translatory manner by means of the actuator unit and is designed to isolate the two contact pieces from one another and then to keep the two contact pieces apart in order to open and to keep open the contact point and to act as an insulator between the contact faces. The actuator unit includes a movement element which is mechanically coupled to the separating element, a drive device which is designed to move the movement element in a first movement direction in order to close the contact point, a device for generating and/or storing kinetic energy, which device is designed to move the movement element and/or the separating element in a second movement direction, which is opposite to the first movement direction, in order to open the contact point, and an electromagnetic actuator.

Disconnecting device for an energy conductor comprising at least one first connection part, at least one second connection part, at least one disconnection point arranged between the first and second connection parts, the disconnection point forming a current path between the first and second connection parts in a closed state and disconnecting a current path between the first and second connection parts in an open state, the disconnecting device having a flowable medium which is arranged in a guide housing and separates the disconnection point driven by a drive, the flowable medium at least partially surrounding the disconnection point at the moment of disconnection, and the disconnecting device having a bolt which is moved into the disconnection point immediately after the disconnection of the disconnection point by the flowable medium.

A switch blocking device that is insertable into an open switch that prevents the switch from being closed, the device being sized and shaped to fit securely in a space between an open blade of the switch and fixed electrical contacts of the switch, the device having a handle that enables easy insertion and removal while also covering the live electrical blade.

An electric contact system includes a moving member movable in a vertical direction, a movable contact mounted on and moved with the moving member, a static contact, and an arc extinguishing device including a movable bracket movable in a horizontal direction and an arc extinguishing sheet mounted on and movable with the movable bracket. The movable contact moves between a switch-on position and a switch-off position. The movable bracket is moved by the moving member between a first position and a second position when the movable contact is moved. When the movable bracket is moved to the first position, the arc extinguishing sheet is moved beyond a contact area between the movable contact and the static contact and allows the movable contact to electrically contact the static contact. When the movable bracket is moved to the second position, the arc extinguishing sheet is moved into the contact area between the movable contact and the static contact to electrically isolate the movable contact from the static contact.

An electrical contact system includes a static contact having a static contact point, a movable contact having a movable contact point, a rotating member on which the movable contact is mounted, and an arc extinguishing device having an arc extinguishing sheet. The movable contact is rotatable with the rotating member between a switch-on position and a switch-off position. When the movable contact is rotated to the switch-on position, the arc extinguishing sheet is rotated beyond a contact area between the movable contact point and the static contact point, allowing electrical contact of the movable contact point with the static contact point. When the movable contact is rotated to the switch-off position, the arc extinguishing sheet is rotated into the contact area between the movable contact point and the static contact point, electrically isolating the movable contact point from the static contact point and cutting off an electric arc.

The arc extinguishing device includes an arc extinguishing member and a driving mechanism for moving the arc extinguishing member. When the movable contact is moved to the switch-on position, the arc extinguishing member is moved beyond the contact area between the movable contact and the static contact so as to allow the movable contact to be in electrical contact the static contact; and when the movable contact is moved to the switch-off position, the arc extinguishing member is moved into the contact area between the movable contact and the static contact such that the movable contact is electrically isolated from the static contact to cut off the electric arc between the movable contact and the static contact. The arc extinguishing member may be driven by the driving mechanism to be quickly moved into the contact area between the movable contact point and the static contact point.
