<p>The invention relates to an electric control device with contacts, used in the electric devices for switching or interrupting the voltage supply connection. According to the invention, the said device is provided with permanent magnets (1, 2, 15, 16, 19, 22, 23, 30 and 32), which provide, by means of the magnetic force interaction, the electric switching or interruption, and for fulfilling the function of circular electric switch, it consists of two magnets (1 and 2) whose magnetic force provides the pressure of the elastic lamella (8), on the conducting piece (9) and the contact plates (10) circularly arranged on a support (3) made of insulating material. According to the invention, the said device has the role of an electric switch, being provided with a rotary magnet (19), placed between two permanent magnets (22 and 23), fastened on a metallic frame (24), the magnetic interaction forces providing the passage from an equillibrium condition to another, and the electric contacts closing or opening, respectively.</p> |
