An electrical switch. The electrical switch includes at least one fixed contact and a movable contact contacting the fixed contact. At least one shutter element is arranged to move in synchronism with the movable contact. The shutter element is positioned in an extended position between the fixed contact and the movable contact and in a contracted position outside the patch of the movable contact allowing the movable contact to turn from the open position to the closed position.

The present disclosure relates to a molded case circuit breaker, and more particularly, to a contact unit of a molded case circuit breaker. A molded case circuit breaker according to an embodiment of the present disclosure may include a fixed contact; a movable contact rotatably provided on a shaft body to be brought into contact with or separated from the fixed contact; and an insulating barrier that enters between the fixed contact and the movable contact during interruption, wherein the insulating barrier is coupled to the movable contact to rotate along a circumferential surface of a shaft body.

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.

A power circuit breaker has a housing defining a first passage and a cross passage through the housing. A bus bar extends through the cross passage and is configured to transmit electric power and/or break transmission of the electric power through the housing. The bus bar includes at least an input section, a coin or center section, and an output section that are separable from each other. The housing aligns a solenoid piston within the first passage of the housing. The solenoid has a piston with two opposite ends, and one of the ends operates as a plunger to separate the sections of the bus bar when the solenoid is actuated. The plunger moves the coin or center section of the bus bar out of contact with the input section and the output section of the bus bar to break electrical transmission across the bus bar.
