FIELD: electrical engineering.SUBSTANCE: in the electric switch current flows through the first (22) and second (32) contact line support. Through output (24) electric current (I) passes in preset direction while through levers electric current (I) passes in the opposite direction and parallel in relation to current (I). Interaction of currents (II) creates repulsive electromagnetic force (F), which is capable to hold levers at a distance from the output thus creating additional compression between contacts. Even though through the second support electric current (I) passes in just opposite direction in parallel to current (I) creation of additional electromagnetic force that could separate the levers from the second contact line support and undesired electromagnetic repulsion is prevented between contacts by means of the first (50) and second (70) ferromagnetic device.EFFECT: simplification and cheapening of the switch structure.18 cl |
