Device for controlling the ignition of gas burners (12) of a domestic cooking appliance, comprising: an electric switch (24) including an insulating casing (26) carrying a pair of fixed electric contacts (28), a movable body (30) carrying a movable electric contact (32) cooperating with said fixed electric contacts (28), wherein the movable body (30) is displaceable with respect to the casing (26) between an open position and a closed position, and an elastic element (34) which elastically pushes said movable body (30) towards said open position, a flexible cable (36) stretched along a rectilinear direction, having a first end (38) anchored to said movable body (30) and a second end (42) anchored to a fixed support, and a plurality of actuating members (50) associated with respective gas taps (14) and having respective movable elements (54) which cooperate with respective sections of said flexible cable (36) and bend according to a corrugated shape respective portions of the flexible cable (36) during the opening of the respective gas tap (14).

A high-voltage earthing switch is disclosed. A static contact of the earthing switch is connected with the first end of a conductive copper busbar. The second end of the conductive copper busbar is connected with a transformer. The conductive copper busbar includes a first segment and a second segment connected with the first segment. The first segment is one straight segment and an end is taken as an end of the first end of the conductive copper busbar. The first segment extends from the static contact in the direction opposite to the instantaneous action direction of the moving contact when the moving contact engages the static contact. The second segment is connected with the other end of the first segment, and extends towards the side of the first segment facing away from the moving contact.

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. The magnetic field of the magnet interferes with the area where the arc occurs and moves with the moving contact along its path, so with a small number of magnets, arc quenching capacity increases. The method of the invention comprises moving a permanent magnet through the area where an electrical arc occurs between a moving contact and a fixed contact, such that the generated magnetic field runs through at least part of the area where the arc occurs.
