Abstract

Power relay with great maneuvering sensitivity, characterized by being constituted by a permanent magnet attached to a fixed support and by an armature attached to the maneuvering member which, in the resting state, is attracted by said permanent magnet in opposition to a spring. traction, by a winding disposed on said permanent magnet that, when excited, is able to create a magnetic field of opposite polarity to that of the permanent magnet in order to reduce the attraction force of the latter and allow the release of the maneuvering member under the action of the dock. The excitation of such winding is effected by means of a DC electric power source by consent of a blocking member that is brought to the saturation state by a command signal amplified in a timely manner by a threshold amplifier circuit.
