<p>A relay particularly for use with printed circuits has a ferrite rotor made up of two parallel portions, to form a symmetrical unit, with commutators at the ends, to rotate in a four pole magnetic field, designed for monostable, bistable or tristable use. It contains at the centre a magnet which can be altered in its orientation from outside. The rotor is of a non-return design.</p> |
