The invention relates to an energy converter (113; 213) having at least one arrangement (16.1, 16.2) for converting mechanical energy into electrical energy, which has an electrical coil (17), a first permanent magnet (18) which is held in a fixed manner in relation to the coil and a second permanent magnet (19) which is movable relative to the coil (17), with which arrangement a change in the magnetic flux caused by movement of the second permanent magnet (19) induces an electrical current in the coil (17) and with which the first permanent magnet (18) holds the second permanent magnet (19) in an idle position by magnetic holding forces, and having an actuation element (114; 214) which is functionally connected to the second permanent magnet (19). To allow a large magnetic holding force in the idle position and thus a powerful, "prompt" actuation of the actuation element to overcome the holding force, according to the invention the two permanent magnets (18, 19) have mutually opposite holding faces (21a, 21b, 22a, 22b) which extend in the direction of the movement path (24) of the movable second permanent magnet (19) and between which the magnetic holding forces act. The invention also relates to a wireless switch having an energy converter and to an arrangement for setting a point of a railbound traffic route with a wireless switch. |
