<p>In this circuit, the controlled vehicles A, B comprise a steering mechanism 2, 9, 10 controlled by two coils 16, 17 which can act on a sliding core 14 coupled in the direction of the vehicle. The core can be placed in one or the other of its end positions by the application of a direct current of one or the other polarity applied to the contact brushes 26, 27 from the circuit track. In one embodiment, for a median position of the core 14, the coils receive in parallel an alternating current which keeps the vehicle in a straight line. The player selects the current applied by means of a hand-held grip. <IMAGE></p> |
