The invention relates to a method and a device for cutting off electric current. The device comprises at least one fixed contact and at least one moving contact that can move between a closed position and an open position, and at least one permanent magnet mounted together with the moving contact, such that the permanent magnet and the moving contact are able to move at the same time.

Abstract

The invention relates to a multiple power switch device, operated by an actuator having rectilinear movement, for alternately opening and closing the electrical connection of the switch poles. Each switch pole is formed by a mobile contact and two fixed contacts, wherein the mobile contacts are formed as a single plate of contacts having upper and lower surfaces, such that when the switch is in the closed position, only the upper or lower surface of each contact of a mobile plate makes contact with the associated fixed contacts from the first and second groups. The relative position between the mobile contact and the fixed contacts of a pole of the switch alternates from one pole to the adjacent poles. The switch is cheaper and easier to produce, and at the same time is able to efficiently quench electric arcs that originate during transient current interruption and closing operations.

The invention relates to a current cut-off switch that can be used for the rapid, effective and complete extinguishing of electric arcs produced in an electric circuit during operations for cutting-off and closing the circuit, making it particularly suitable for cutting off direct current. The switch comprises at least one pair of fixed contacts (4, 4') and a moving contact (9) mounted in a rotor (2) made from insulating material, in which the rotor (2) is designed to move linearly in relation to the fixed contacts. The switch can be reconfigured, since during the transient current cut-off process the internal contacts of the switch are connected in series and during the permanent current conduction state of the switch the same contacts are connected in parallel.
